Basic concepts forbusbarsThe busbar is the most modern solution for the distribution ofenergy in an installation for machinery, equipment and lightingfittings, in all types of buildings such as warehouses, tradefairs, or any place where the pace of installation operationsprovide tangible benefits immediately, but also continueto cumulate benefits at every maintenance intervention ormodification. The busbar is also frequently used to powerthe (horizontal and vertical) backbones of buildings usedfor the commercial-service sectors, thus observing the timerequired for the installation and providing a final solution withremarkable technical advantages compared to an equivalenttraditional system made with cables.Zucchini’s busbars, available in 3 segmented ranges (LowPower, Medium Power and High Power), are able to meet allinstallation requirements, from 25A to over 5000A.BUSBAR

EASY TO DESIGNThe electric design of the busbars is achieved byZucchini in compliance with the product Standards.The rated current of our busbars is guaranteed ata room temperature of 40 °C (n.d.r. the Standardrequires 35 °C). After choosing the busbar whichis able to meet the operating current regulations, itwill be very easy to verify the voltage drop as wellas the protection against overcurrents by using thetechnical tables available for all our production lines.In particular, these tables define: the short circuit andpeak currents that can be supported by the busbarwaiting for the protection device located upstreamto start operating, the specific voltage drop basedon the average cos phi of the loads, the losses andother data (R, X, Rpe, etc.) which allow the planningengineer to carry out calculations with electricvalues, which are not estimated but the result ofmeasurements made during heating and short circuittests (in certified LOVAG laboratories), which havecertified all our product lines.When using busbars, the load protection is locatedvery close to the device (decentralized protection);junction boxes can contain protection devices such asthermal magnetic circuit breakers, fuse carriers andmotorized switches which allow you to easily andefficaciously manage the system.Example of an electric characteristics tableINTRINSIC SAFETYA busbar does not use large amounts of insulatingplastic material and potentially dangerous materialsin case of fire. Furthermore, the plastic materials usedfor the insulating parts of the busbars are alwaysself-extinguishing (from V0 to V2) and the gasemission is generally very low (Halogen Free).Low electromagnetic emission is another advantageof the busbars compared to that of an equivalentcable system: as a result, the metal plate casingof the busbars serves as a screen for the electricfield (shielded enclosure); the extreme vicinitybetween the phase conductors also reduces theemission of the magnetic field considerably. TheItalian law, according to the DPCM (Prime MinisterialDecree) of July 8th 2003, sets the “target level” to10 μT and the “quality level” limit to 3 μT. The testscarried out on one of our 2500A SCP busbars at fulloperating current has shown that the emission of themagnetic field (magnetic induction) is lower than the“target level” of the Decree at a distance of 0.3m,whereas the threshold considered as the “qualitytarget” can be achieved at a distance of only 0.7mfrom the busbar. These features make our busbarsthe unavoidable choice for hospital facilities, dataprocessing centres and wherever it is necessary tosupply a large amount of power in the vicinity ofworkplaces and/or sensitive equipment..Zucchini busbar electromagnetic emission.GENERAL FEATURES5LOW-MEDIUM POWER GENERAL CATALOGUE

Basic concepts forbusbarsFLEXIBILITYBy using the outlet windows locatedon the straight elements, the busbarsprovide high management flexibility,both when planning (electricalengineer) and when installing thesystem (installer); they are also usedfor the unavoidable changes requiredby the electric system to adapt to thevaried needs of the end user. Thejunction boxes can be inserted andremoved from their windows whenthe busbar is electrically poweredand inserted in another junctionwindow, thus avoiding downtime.The engineering department in chargeof designing the busbar does not haveto know the exact position of themachinery and of the electric loadsthat will be installed in the company;the project that will be carried out willbe open to changes and variationswhich will be defined by the end userwhen operationally using the system.No more point-point connections butonly one power distribution systemto which you will always be able toconnect to wherever there is a freewindow. Because of its flexibility anddurability features Zucchini’s busbar,installed inside a building, allows youto easily change the destination ofits intended use of the rooms, thusgiving also advantages to those whomanage and locate the various partsof the building premises.Busbar systemCable and tube lighting systemBUSBAR

QUICK INSTALLATIONZucchini’s junction and fixing systemshave been designed and created to installbusbars easily. In a cable and tray system,the time required to install only the tray isthe same used to install a complete systemin busbars. Furthermore, given the samecapacity, a power busbar, which generallyhas aluminium conductors, is much lighterthan a system made with (copper) traysand cables: lighter weights require a lowernumber of supporting frames or, in any case,more simple and inexpensive supportingframes. That is why the installation time ofa busbar is obviously shorter than a similarsystem made with cables.REDUCED DIMENSIONSThe overall dimensions of the busbars aregenerally smaller than an equivalent systemmade with cables, especially when the currentsto be carried exceed 1000A and when severalcables in parallel are necessary to ensure suchcapacity. Other advantages can be achievedwhen there are changes of direction where theradius of curvature of the cables is minimal andenough to not damage the insulating material;busbars allow you to change directions with 90°angles, thus optimizing the small spaces used inservice areas.GENERAL FEATURESLOW-MEDIUM POWER GENERAL CATALOGUE

The innovative system for thedistribution of energyEASYBAR is the perfect solution for the distributionof energy within any service and industrial sector. Itsmaximum height of only 50mm, the thinnest onthe market, makes it an exclusive and innovativeproduct.With EASYBAR, it is possible to distribute 25A or 40Acurrents, maintaining an IP55 degree of protectionwhen the installation is complete. The elements areavailable in 2m and 3m lengths.EASYBAR can be positioned:• under the raised floor• On the wall to outfit work stations• in the interspaces of the dry wall plasterboard• in the false ceiling2 EB - EASYBAR

EBEASYBARFLOOR INSTALLATIONEASYBAR busbars, because of its reduced50mm height (with accessories installed),can be positioned in particularly low raisedfloors. It is suitable for new installations aswell as for renovations in which it is notpossible to raise the floor.By using tap-off plugs, which can bepositioned anywhere on the trunking,it is also possible to connect Legrand fastconnectioninstallation system products suchas floor boxes, mini columns and multipleoutlet extensions, which can be combinedwith the Cablofil type wire mesh cabletrays system used for the data networkdistribution and safety circuits.CEILING INSTALLATIONThank to the innovative tap-off plugs,EASYBAR is well suited for distribution ofenergy for lighting in false ceilings.Specific tap-offs for each phase allow todistribute an even load and quickly connectthe lighting fixtures.GENERAL FEATURESLOW-MEDIUM POWER GENERAL CATALOGUE3

AdvantagesThe EASYBAR system has been studied to makeinstallation operations easier and quicker. Whenusing EASYBAR, unlike a traditional energydistribution with trunking lines and cables, theinstallation time can be reduced by using the snap-oncomponents and through the possibility of creatingthe lines in 2 ways:1 - by first positioning the fixing clampingbrackets onto the mounting surface, andthen clipping in the straight element.With this installation method, all brackets need tobe put in the line roughly or with laser tools2 - by positioning the brackets onto thebusbars and then fixing the product.The side fastening system gives you theadvantage of having the brackets already alignedby the straight element.MAX.50 mmENERGY TAP-OFF WHEREVER YOU NEED ITThe tap-off plugs have been designed to be positioned atany point on the busbar for complete modularityREDUCED DIMENSIONSOne of the main advantages of this innovativesystem is its size:• the height of the busbars is 17mm• Maximum height with the componentsmounted is 50mm.IP55 PROTECTIONThe degree of protection of the whole EASYBARsystem is IP55 after completing the installation,but thanks to the innovative design, even duringinstallation, if an end cover, joint or covering fiIm ismissing, an IP2X protection is always guaranteedagainst direct contact.4 EB - EASYBAR

EBEASYBARUP TO 7 TAP-OFFS PER METREPossibility to install up to 7 tap-offplugs per metre, thus allowing acomplete utilisation as well as awidespread distribution of energy fordifferent configurations.EASY AND QUICK INSTALLATIONThe snap-on system reduces the installation timeconsiderably.CONVENIENT IN EVERY WAYOnly one element and few installation accessoriesthat guarantee an easy, fast and inexpensive distributionof energy.RESISTANCE AND SAFETYEASYBAR is particularly resistant; in fact the straightelements can be stepped on without damagingthem. EASYBAR gives you the possibility of agood, safe installation when worksite jobs arebeing started. With the safety lock system, evenunder load, a worker can isolate a line to work incomplete security. Thus even during installation ormodifications, potential accidents are avoided withEASYBAR.GENERAL FEATURESLOW-MEDIUM POWER GENERAL CATALOGUE5

Installation SOLUTION:traditional or EASYBAR?A traditional energy distribution system requires theuse of trunking systems as well as multiple cables.There are various installation operations whichare carried at different times, thus prolonging theinstallation and testing time and hence with increasesin cost.By using the innovative EASYBAR system, theinstallation time is greatly reduced, thus facilitatingreliable project management and planning.Furthermore, EASYBAR is easily integrated both with theCablofil cable tray system and with Legrand products fordistribution in offices and all commercial applications.The busbar can be simply clipped onto the same wiremesh cable tray used for the data VDI structuredcabling system.The worksite is a extremely severe environmentduring the installation stage, with all trades comingand going continuously, so EASYBAR was conceived asa very resistant product: it can even be stepped on,allowing the installation without waiting for the floor– this factor shall be taken into consideration as manytypes of underfloor trunking systems do not have thislevel of robustness.The following table illustrates the cost effectivesolution of EASTBAR compared to traditionaldistribution.INSTALLATION STAGESDescription Traditional EASYBAR The advantages of using EASYBARSystem planning √ No It is not necessary to know in advance howmany work stations there will beDerivation points √ No If it is necessary to add new stations, all you need todo is install the tap-off plugs on the straight elementMaterial order √ √ Limited only to the straight elements, plugs,brackets and to the power lockTrunking installation √ No The snap-on system allows busbar ducts to beinstalled easily and quicklyWiring devices √ No No need for derivation boxes and terminal stripsto be cabled each time, just plug in where thederivation is neededCable insertion √ No When using Legrand fast connection plugs it ispossible to connect EASYBAR tap-off plugs to theLegrand Fast Connection distribution system easilyand quicklySystem testing √ √ There is no risk of having disconnections due tocable failureFlexibility No √Possibility of being stepped on No √ EASYBAR can be stepped on and has a degreeof protection IP55 after completing the installation6 EB - EASYBAR

GENERAL RULES FOR INSTALLATIONThe EASYBAR system is very easy and fast to install.In fact with few operations and with all the snap-onaccessories it is possible to create a complete floor, ceilingand wall energy distribution system. The following pagesdescribe the basic operations for the installation of thebusbar and for the distribution of energy in differentpoints. Remember that the EASYBAR distribution systemis part of the Legrand solution for the workstations: It isthe integrated electrical backbone for the DLP columns,mini-columns and floor boxes alongside the Cablofil cabletrays for the VDI structured cabling system. Rememberthat the maximum height of 50 mm (elements andplugs/feed units installed) allows EASYBAR to be used ineven the most restrictive modern day installations.INSTALLATION OF THE BUSBARSFor the electrical distribution, there is no need tofollow the office layout of the furniture. Generallyspeaking, in order to guarantee the most completeand flexible distribution system under the raised flooror on the ceiling, parallel backbone distribution runsare used.The creation of an EASYBAR layout can be carried outwith two methods, making use of two fixing brackets(item 74003700 and item 74003001):• the first method (traditional) is to make use of thefixing bracket item 74003700 where elements areplaced on the floor, without the busbar, and set inline with laser indicators. The busbar will then bepositioned accordingly. This is the most classicalsolution but it is also the most difficult because theinstallation needs to be carried out in two steps(figure 1),• the second (the fastest) method can be carried outin one step, that is to make use of fixing bracketsitem 74003001. This accessory is first installeddirectly on the busbar and then positioned on thefloor so that it can be fastened. This solution ispossible because the bracket is fastened on oneside, hence the hole is not obstructed by the busbar.By making use of this solution, the installation timewill be reduced. The busbar will help you to line upall fixing brackets in line (see figure 2).Figure 1CLACKFigure 212 EB - EASYBAR

HLHigh LightingGENERAL FEATURESThe HL busbar line is ideal for powering lightingfixtures wherever it is necessary to hang heavyaccessories onto the busbar. The main features of theHL range are:• speed, simplicity and flexibility when installing andplanning the lines;• high mechanical rigidity obtained by the particular“beam-type configuration” and by an increasedthickness of the metal casing;• capable of being installed in systems with adistance of up to 6m between suspension brackets;• compliance with Standard IEC 60439-1 and 2;• rated at average room temperature of 40°C for ahigher performance level compared to the 35°Crating required by the standard.HL is available in two dimensions:• HLs single version for 2 and 4 conductors• HLd dual version for 2+2; 4+2; 4+4 and 2x4conductors.Straight elementTap-off plugClamping bracketStandard end feed unitExhibition pavilionsCar parks38 HL - HIGH LIGHTING

STRAIGHT ELEMENTSThe components and the features of the HL straightelements are:• a beam-shaped casing, made with hot galvanizedsteel (Senzimir) (due to its cross-section andelectrical continuity, it also serves as the protectiveearth).• HLs busbar dimensions: 26x62mm; HLd: 40x70mm;• upon request, the straight elements are alsoavailable in the Aisi 304 stainless steel version;• number of conductors: 2, 4, 6 or 8 rigid copperconductors with a 99.9% purity;• conductor section: 3.14 mm 2 for 25A and 6.15 mm 2for 40A.;• separation between the conductors by using a V0(according to UL94) self-extinguishing insulatingplastic sheathe and in compliance with the glowwiretest according to IEC 60695-2-10;• tap-off outlets equidistant every 1m (3 outletsevery 3m) or 0.5m (6 outlets every 3m), receivingthe corresponding tap-off plugs (in the LB 6conductor version the outlets are arranged on bothsides of the busbar: 3+3 or 6+6 outlets);• a junction block automatically ensuring electricalcontinuityThe connection between two straight elementsis quick; with one operation the mechanical andthe electrical connection is ensured between twojoined elements; at the same time, an IP55 degreeof protection is guaranteed without using additionalsealing accessories.The continuity of the protective conductor (casing)is guaranteed by tightening the special connectionscrew.The whole busbar is fire retardant in compliance withthe Standard IEC 60332-3.In the HLd (dual) version, the straight elementsare separated over their entire length by a metalplate divider (thickness 0.8 mm) which separatesthe straight elements in two parts making the twocircuits totally independent. Because of this divisionthe HLd busbar can be used for powering “normal”and “emergency” loads.The HLd line is designed so as to provide twoseparate rated circuits (25A+25A or 40A+40A) onwithout a derating factor, and not one one 25 or 40Aincoming divided into two circuits.HLHIGH LIGHTINGSmall/medium industriesGymsGENERAL FEATURESLOW-MEDIUM POWER GENERAL CATALOGUE39

HLHigh LightingFEED UNITSAllows you to electrically power the HL line throughone (HLs) or two separate lines (HLd); the installationis carried out with a quick junction connection as withthe straight elements.The feed units have terminals for the connection offlexible cables for sections of up to 25 mm 2 . There isan anti-pullout cable clamp inside the feed unit. Theentrance point for the incoming cable is positionedon the end of the feed unit.Standard end feed unitEND COVERThe end cover ensures the IP55 protection degree atthe end of the line.Standard end coverFIXING DEVICESSpecific accessories are available for attaching thebusbar to the structure of the building (directly orwith a steel chain or cable). The accessories foroverhead fixing are:• snap clamp: the snap-on installation is extremelyfast. This bracket is suitable both for overhangingthe busbar to the ceiling and for hanging productssuch as fluorescent lamps, tap-off boxes, etc., tothe busbar itself;• snap clamp with ring or hook: the ring or the hookenables to hang lamps easily;• simple bracket: used with the ceiling bracketholder, it enables the installation the busbardirectly onto the ceiling at a distance of about25cm;• wall bracket: enables the fixing of the busbardirectly onto the wall of a building, setting it at therequired distance enabling the installation of thenecessary components.Fixing accessories for fastening the busbar run to thestructure and hanging the lamps onto the busbar40 HL - HIGH LIGHTING

TAP-OFF PLUGSUsed for connecting and energizing light fixtures; theirfeatures include:• can be inserted and removed when the busbar isenergized and when the fixure is under load;• the PE contact (protective earth) is the first to make anelectrical connection when inserting the plug into theoutlet and it is the last to disconnect when pulling itout;• all insulating plastic components are in compliancewith the glow-wire test (IEC 60695-2-10) with V1 selfextinguishingdegree (UL94);• standard IP55 degree of protection without usingadditional accessories according to Standard IEC 60529;• in the HLd line, the plugs are polarized, in otherwords the plug which is busbar on one side of theelement cannot be installed on the other side due to amechanical lock on the outlet;• the tap-off plugs are different for the HLs 2, 4 andHLd 2+2, 4+2, 4+4; 2x4 conductors offer. They include:a) 16A phase selection tap-off plugs, pre-wired with 1mof 3x1.5mm 2 FROR cable;b) 16A phase selection tap-off plugs, with terminals forconnecting a cable;c) 16A phase selection tap-off plugs, with ø5x20mmcylindrical ceramic fuse and with terminals forconnecting an L+N+PE cable;d) 16A three-phase tap-off plugs, with a set of threecylindrical fuse carriers (8.5x31.5mm) with terminalsfor connecting a 3L+N+PE cable.HLHIGH LIGHTINGSingle-phase selection plugPlug with fuse carrierGENERAL FEATURESLOW-MEDIUM POWER GENERAL CATALOGUE41

Trunking components andadditional elementsDepending on the different installation requirementsZucchini can provide various technical solutions:a) flexible joint: used to make changes of direction orto avoid possible interferences that may be found onthe path of the busbar.Their main technical features are:• same connection method as the straight elements;• electrical and mechanical connection with oneoperation;• standard degree of protection: IP55;• continuity of the protective conductor, made from thecasing of the element itself, guaranteed by tighteningthe special connection screw;b) cable trunking with cover: this accessory, whichcan be positioned in the upper part of the busbar,can be used to distribute auxiliary circuits, it is anintegral part of the busbar run using special spacersand brackets which support the busbar trunkingsystem firmly. The trunking part is 3 m long and itsdimensions are 28x28 mm;c) intermediate feed unit: it can power the busbar froman intermediate point of the line, thus reducing thevoltage drop at the end of the line and/or makingthe installation easier when the electric energysupply point is near the middle of the line.The end capcompletes theinstallation of thelines and guaranteesthe IP55 degree ofprotection of theline.Straight elements, withtap-off outlets every1000 mm on bothsides, with pre-installedblanking accessory.Phase selectiontap-off plugs, alsoavailable with fuses.Ring for suspending alamp or for suspendingother accessories ofthe busbar.

MRTechnical descriptionFEED UNITSAllows you to electrically power the MR line througha cable line or directly connected to an electricdistribution board. The 160 and 250A feed unitshave terminals for cables up to 150mm 2 ; for higherratings, the cable connection to the feed unit requirescable lugs to be fastened to the provided spreaders.The MR line can be provided with centre feed unitsor end feed units with a switch-disconnector whichallows you to isolate the whole line for carryingout maintenance operations or layout changes, ifrequired.Feed unitEND COVERThe end cover ensures the IP55 protection degree atthe end of the line.End coverFIXING SUPPORTSIn order to fix the line to the structure of the building,directly or with wall / ceiling / beam supports, it isnecessary to use the bracket supports or verticalsuspension supports.Suspension bracket for verticalelements92 MR - MEDIUM RATING

TAP-OFF BOXESUsed for energizing three-phase loads from 16A up to1000A; they can be divided into two big categories:1) Plug-in type tap-off boxes (from 16A up to 630A)with the following features:• Intervention under load possible up to 32A;• disconnection device integrated into the cover ofthe boxes with a rating from 63A to 630A, ensuringautomatic absence of electric current when the coveris opened;• possibility of padlocking box cover in the opendisconnectedposition so that all maintenanceoperations of the loads connected to it can be carriedout safely;• the supplied PE contact (protective conductor) is thefirst to make an electrical connection when insertingthe box into the outlet and it is the last to disconnectwhen pulling it out;• all insulating plastic components are in compliancewith the IEC 60695-2-1 glow-wire test and rated V2self-extinguishing according to the UL94;• standard IP55 degree of protection without usingadditional accessories;• availability of boxes in the following versions:- with a set of three fuse carriers- with Lexic MCBs- with EEC sockets and Schuko sockets- with AC23 switch disconnector and fuse carrier- for MCCBs.2) Boxes bolted onto the connection (from 630A to1000A) which include the following features:• very easy, fast and reliable installation;• high rated current;• rigid connection to the busbar through the use of amonobloc junction similar to the straight elementsystem;• possibility of removing the boxes only when thebusbar is not energized (isolated busbar);• availability of boxes in the following versions:- AC23 switch disconnector and fuse carrier- with MCCBsMRMEDIUM RATINGTap-off box with the possibility of installingmodular circuit breakersTap-off box with integrateddisconnecting deviceGENERAL FEATURESLOW-MEDIUM POWER GENERAL CATALOGUE93

Trunking components andadditional elementsDepending on the different installation requirementsZucchini can provide various technical solutions:a) 90° elbows: available for carrying out changes ofdirection both horizontally and vertically. There is aquick connection, as for the straight elements.The standard degree of protection is IP55;b) T-type and X-type elements, Z-type double elbowsavailable. The standard degree of protection is IP55;c) straight elements with fire barrier (internal +external) S120 (certified for 120min).Tested in laboratories (in compliance with DINStandards 4102-9 and EN 1366-3) to confirm that,correctly installed, they maintain the intrinsic fireresistantproperties of the wall;d) straight elements with 5 outlets on one side; theyare ideal for riser mains or segments with a largenumber of derivations;e) straight elements with no outlets, used for energytransport only.The MR line is even more advantageous in verticalapplications (riser mains) as no thrust unit or thermalexpansion element is necessary. The MR monobloc isdesigned to compensate the thermal expansions of theconductors.IP55 joint cover.Straight elements, with tapoffoutlets every 1000 mm.on both sides.Suspensionbracket.Tap-off box.PARTS OF THE LINEMetal end feed unitSwitchboard - transformer feed unitHorizontal angleVertical angle94 MR - MEDIUM RATING

AdvantagesPRE-ASSEMBLED MONOBLOCAll trunking components (straight elements, angles, etc.) are provided witha pre-assembled monobloc which considerably speeds up the installation ofthe system and makes transportation and storage operations easier.EXTREMELY FAST INSTALLATIONThe monobloc and the “dynamometric” bolt allow a very fast installation ofthe whole line.DYNAMOMETRIC MONOBLOCTighten the “dynamometric” bolt on the monobloc until the head breaks toelectrically connect the elements. The breakage of the bolt head guaranteeslong-lasting reliability and safety.The connection is maintenance free.In case of a future intervention on the line, the monobloc must beretightened using the second bolt head with a torque wrench at the correctsettings: 34 Nm (up to 315A Al / 400A Cu) or 55 Nm (up to 800A Al / 1000ACu)96 MR - MEDIUM RATING

CONNECTION FLANGESIf the monobloc has been tightened improperly, the head of thedynamometric bolt will prevent the mechanical coupling from closing. Theconnection flanges and the seals serve as a protection for the elementduring transportation and ensure their degree of protection as well as theirmechanical rigidity when being installed.IP OF PROTECTIONThe MR line on “edgewise” position has a standard IP52 protection degree;by simply adding the plug-outlet covers to the tap-off outlets, the line canreach an IP55 degree of protection.MRMEDIUM RATINGEXCELLENT FIRE RESISTANCEThe MR line has elements provided with a flame barrier (S120 accordingto DIN 4102-9 ISO 834) and structures which guarantee that the bus-linecontinues to function in case of fire (E120 according to DIN 4102-12).The fire load of the MR line is extremely low compared to the quantity ofplastic materials needed to insulate cables with the same capacity.CATALOGUELOW-MEDIUM POWER GENERAL CATALOGUECATALOGO CONDOTTI SBARRE97

AdvantagesGLOW-WIRE TESTAll plastic materials are resistant and in compliance with the “glow-wire”test (IEC EN60439-2).VERSIONSThe MR symbol indicates a busbar with 4 conductors with an equal crosssection (3L+N), and the casing acts as the protective earth conductor (PE);the MRf (full) line has 5 conductors with an equal cross section (3L+N+PE).The MR and MRf lines are also available on request in a painted version (RALto be defined by the customer).SIMPLE AND RELIABLEThe “monobloc” connection of the MR line is able to compensate for anyheat expansion affecting the conductors, thus avoiding the need to insertspecial expansion elements even in considerably long systems.If the MR line is installed vertically (riser main) there is no need to installbusbar thrust units because the monobloc prevents the conductors fromsliding.98 MR - MEDIUM RATING

COMPATIBLE WITH THE SB RANGEThe tap-off boxes of the SB range can be installed without any modificationson the MR range. This allows existing systems to be extended.MAXIMUM STRENGTHThe MR range has been designed and manufactured for heavy industrialenvironments.

TSTechnical descriptionGENERAL FEATURESThe TS (Trolley System) is part of the Zucchini rangeused for supplying power to moving devices such as:overhead cranes, traversing motors, assembly lines,etc.The main features of the TS range are:• quick installation thanks to the electric terminaljunction;• wide range of fixing accessories;• suitable for straight and curved sections (only forhorizontal changes of direction);• compliance with Standard IEC 60439-1 and 2;• rated at average room temperature of 40°C for ahigher performance level compared to the 35°Crating required by the standard.• available in the following versions: 3L+N+PE (5conductors) for ratings from 63-70-110-150A and3L+PE (4 conductors), for 250A rating in which theloads connected are normally three-phase motors.Automated warehousesCranesSuspension bracketStraight elementTrolleyFeed unit126 TS - TROLLEY SYSTEM

STRAIGHT ELEMENTSThe components and the features of the TS straightelements are:• casing made with a hot galvanized steel (Senzimir);• sheet metal thickness: 1.2 mm (1.5 mm for 250A);As for the 63A (MTS63) rating, the casing is madeof extruded aluminium with a minimum thicknessof 1.4 mm; it has good mechanical rigidity andpreserves its linearity over time.• number of conductors: 5 conductors with the samesection 3L+N+PE (4 for the TS 250A), shaped toguarantee excellent mechanical strength. Theconductors are made of 99.9% pure electrolyticcopper;• separation between the conductors using fibreglassreinforced plastic material ensuring a V1 selfextinguishingdegree (according to UL94) and incompliance with the glow-wire test according toIEC 60695-2-10;• the slot along the underside of the busbar allowsa current trolley to slide in it. The size of the slotensures an IP20 degree of protection;• an independent electrical junction terminal system(made of bronze plates) for fast and reliableconnection of the live conductors and the PE. Theterminals make an electric connection between theconductors, with a smooth flat lower part in orderto make the trolleys slide more easily. The wholebusbar is “fire retardant” in compliance with thestandard IEC 60332-3.Work station installationInstallation for mobile machineryTSTROLLEY SYSTEMCrane installationGENERAL FEATURESLOW-MEDIUM POWER GENERAL CATALOGUECATALOGO CONDOTTI SBARRE127

TSTechnical descriptionFEED UNITSAllows you to electrically power the TS busbarthrough a cable line; the installation is carriedout with a quick terminal connection as with thestraight elements. The entrance point of the cablesis generally positioned on the back side of the feedunit. The TS range has centre feed units which can beinstalled wherever there is a junction between thestraight elements.Feed unitIntermediate feed unitEND COVERThe end cover ensures the IP55 protection degree atthe end of the line.End coverFIXING SUPPORTSIn order to fix the line to the structure of the building,directly or with wall / ceiling / beam supports, it isnecessary to use a bracket which serves as a collararound the busbar. An electrical junction, which canalso serve for suspending the busbar, is available onthe TS line. The bracket has holes so it can be easilypaired with the supports available in the Zucchinicatalogue.Coupling clamp with suspension bracket128 TS - TROLLEY SYSTEM

TROLLEYSThese are used for connecting and supplying powerfor 25A – 40A – 80A or 160A three-phase loads (in thecoupled version); their features include:• The trolleys are equipped with 5 graphite brushes(3L+N+PE) which, due to the spring action, keep thecorrect pressure on the conductors enabling themto pick up current from the line while the trolley ismoving (travelling) inside the TS busbar.• The trolleys can be coupled with a mechanical joint soas to pickup twice the rated current of a single trolley.• The trolley is coupled to the motor with a “drive arm”which receives the movement from the same electricmotor supplying power to it.• The drive arms are connected to the trolleys withspecial springs which reduce the acceleration(so-called “sudden pulls”) when starting up and whenbraking;• Maximum travelling speed of the trolleys is 90 m/min(150 m/min for the MTS 63A).• Availability, on request, of a box with a set of threefuse carriers, used as an accessory, to protect the cablefrom overcurrents.• compliance with all insulating plastic componentsaccording to the glow-wire test (IEC 60695-2-10) withV1 self-extinguishing degree (UL94).• Standard IP20 degree of protection without usingadditional accessories.40A trolleyTSTROLLEY SYSTEMGENERAL FEATURESLOW-MEDIUM POWER GENERAL CATALOGUECATALOGO CONDOTTI SBARRE129

Trunking components andadditional elementsDepending on the different installation requirementsZucchini can provide various technical solutions:a) curved elements: available for making changes ofdirection (only horizontally) up to a minimum radiusof curvature of 1.5m. There is a quick connection,as with the straight elements. Standard trolleys slideefficiently even within the curved sections of the line.The standard degree of protection is IP20;b) straight elements with trolley introduction device:these elements are provided with an access dooron the underside. With this door open, it is possibleto insert or remove a trolley from the line. Trolleyscan generally be put into the line near the endcovers. However, when there are lines with severaloperating trolleys or when using very long lines, it isrecommended to use an inserting centre element tomake maintenance operations on the trolleys easier.The standard degree of protection is IP20;c) straight lengths with thermal expansion device.These elements are necessary in lines exceeding35-40 m in length.

RESINUsed for encapsulating medium-voltage windings:it is of the epoxy type filled with silica andtrihydrate alumina. The resin is treated in highvacuum chambers to obtain optimum degassing toreduce the presence of air or other gases, to avoidpartial earth discharges. The epoxy compound ischaracterised by optimum di-electric and mechanicalproperties, able to resist the various stresses towhich the transformer may be exposed throughoutits life. When using the special epoxy resin alongwith a targeted project, all EdM transformers areclassified E2-C2-F1 (Certificate of conformity CESI No.98/012355).COREThe magnetic core is made of sheets of laminatedgrain oriented magnetic steel with loss figures,depending on the actual design specifications.The core, totally designed by EdM, is purchased atselected suppliers which guarantees optimum qualityof the product as well as a no-load loss certification.11134121 - MV windings in aluminium strip coils, cast in resinunder vacuum.2 - Core in three columns in magnetic lamination withhigh-permeability oriented crystals3 - LV windings in aluminium plate/sheet and vacuumcastimpregnated insulation material.4 - LV connections upwards5 - MV connections upwards6 - Rubber inserts attenuate the transmission of vibrationsbetween core and windings and reduce to a minimumthe operating noise generated by the transformeras well as absorbing the thermal expansion of thecomponents.7 - Sockets on the MV side to adapt the primary voltage tothe mains, which can be set with transformer switchedOFF.8 - Structure, armatures and carriage, made in strongpainted sheet steel.9 - Carriage with bi-directional castors.10 - The epoxy resin insulation has a high flashpoint andhigh self-extinguishing11 - The operating temperature is checked by Pt100 sensoror PTC in the LV windings12 - Lifting eyebolts conform to the DIN-580 UNI-2947standars with safety hooking at 4 points.13 - Optional pre-equipment for connection of the LVconnection Zucchini busbar trunking system.14 - Class F insulating material, at 155°C, allowing for atemperature rise of 100°K.15 - The carriage allows safe movement and is preequippedfor the mounting of an IP reinforced boxes.657812310 14CRT - CAST RESINTRANSFORMES9 15GENERAL FEATURESLOW-MEDIUM POWER GENERAL CATALOGUECATALOGO CONDOTTI SBARRE159

CRTTransformers Technical descriptionMEDIUM-VOLTAGE WINDING (MV)Medium-Voltage windings are made on highlyautomated winding machines and are made withaluminium strip conducting material. The windingis continuously performed directly on the internalshape of the mold onto which there is a fiberglassnet used as a static support for the winding. Thisnet prevents the misalignment of the aluminiumwinding disks during the various stages prior tothe insertion in the casting system. This type ofprocess enables the EdM transformers to keepthe thickness of the resin consistent both insideand outside. It also ensures constant mechanicalresistance to di-electric stresses to which thetransformer is exposed both during the testingphase and during its technical lifetime. Off load tapchangers of the primary voltage +/-2 x 2.5% areused on the primary winding. The thermal classof the insulating materials used conforms to classF and the permitted temperature rises are thosespecified in the specific product Standards.Electronically controlled winding machineLOW-VOLTAGE WINDING (LV)The Low-Voltage winding is made from an aluminiumsheet whose height is the same as the coil. Thewinding is formed using special winding machinesthrough a process which ensures a compactness ableto form a single cylinder. Compactness is essential towithstand the axial and radial stresses resulting fromshort-circuit phenomena to which the transformermay be required to deliver. All the welds of theconducting sheet (plate) along with the connectiontaps are butt welded (inert gas) to prevent anywelding remnants from affecting or damaging theinsulation placed between the coil end and the nextcoil. The LV winding is suitably treated (vacuumepoxy resin dipping) to avoid the absorption ofmoisture throughout its life. This treatment is suitablefor any environment in which the transformer is tobe used, including those with a high humidity value(tropical or sea environments), thus allowing for theF1 classification of the system in compliance with thespecific product Standards.TIG welding in controlled atmosphere for LV connections.160 CRT - CAST RESIN TRANSFORMER

ProtectionsystemsAll transformers are protected against possibletemperature rise risks resulting from extendedovercharge phenomena and improper ventilationof the rooms where the machine is installed. Theprotection is achieved through a PT 100 Ohm triadof platinum thermal resistances (one for each LVcolumn) which communicate with a temperatureviewing and monitoring apparatus (control unit).The unit is supplied as a separate part to be installed,if required, on the control panel. By following theoperational instructions supplied with the EdMtransformer, you can use the unit to programme thetwo temperature values corresponding to the “alarmlevel” and to the “disabling level” of the transformer.The two levels are based on the thermal class of theinsulating materials used for making the MV and LVcoils.E2 C2 F1ENVIRONMENTAL TESTS CLIMATIC TESTS FIRE RESISTANCEEnvironmental class E2It confirms that the productis suitable for installation inenvironments with condensationand/or high pollution.Climatic class C2The transformer can be transportedand stored down to -25° C.Class F1Fire BehaviourIt confirms that the productis suitable for installation inenvironments with high fire risk.The transformer is made fromself-extinguishing materials.Low voltage terminals MV coils Magnetic Core step - lapCRT - CAST RESINTRANSFORMESGENERAL FEATURESLOW-MEDIUM POWER GENERAL CATALOGUECATALOGO CONDOTTI SBARRE161

Determination of the operatingcurrent of a busbarIn order to determine the current whereby it is necessary to choose the busbar,the following planning data must be known: ϕ of loads which are to be fed by the busbar; VOLTAGE DROPΔv% = bdefinedI bVnLΔv%αβkI b=[A]√ϕ mediumb =2b =1ex: MR 160I b=15 20 25 30 35 40 45 50 55 601.15 1.12 1.08 1.05 1.025 1 0.975 0.95 0.93 0.89I nt≥ I bI nt= k 1 nWhen using a three-phase power supply, the operating current is determinedby the following formula:where:I boperating current [A];α load diversity factor [.];β load use factor [.];d feed factor [.];P TOTsum of the total active power of installed loads [W];Ue operating voltage [V];cosϕ mediumaverage load power factor [.];The “d” input factor has a value of 1 when the busbar is fed from one end only.The value is 1/2 if fed from the centre or if it is fed from each end.Once the operating current has been determined, choose the busbar with a ratedcurrent immediately higher than the one calculated.All Zucchini products have been designed and tested for an average roomtemperature of 40°C; should they be installed in rooms with average dailytemperatures different from 40 °C the rated current of the busbar should bemultiplied by a k1 factor that is greater than the unit for temperatures lower than40°C and lower than the unit if the room temperature is higher than 40°C.Roomtemperature [°C]k 1thermal correctionfactor [.]Finally, the following should be considered for the most appropriate busbarchoice:where I ntrepresents the maximum current loaded by a busbar for an indefinitetime at the specified room temperature.JOULE EFFECT LOSSESLosses due to the Joule effect are essentially caused by the electrical resistanceof the busbar. Lost energy is transformed into heat and contributes to theheating of the conduit.If the length of the line is particularly long (>100m) it is necessary to check thevoltage drop (hereinafter specified as v.d.).
