Economical, Requirement-Oriented, Type-Tested<br />
<strong>sivacon</strong>
Economical, Requirement-Oriented and Type-Tested:<br />
the SIVACON Variable Low-Voltage Switchboard<br />
Economical, requirement-oriented and<br />
type-tested (TTA) – these are the identifying<br />
features of the new low-voltage switchboard<br />
from Siemens. SIVACON®is suitable for<br />
all power levels: from the power centre<br />
with a rating of 6300 A through main and<br />
subdistribution boards to the motor control<br />
centre, installed either in fixed-mounted,<br />
plug-in or withdrawable unit design.<br />
Modular technology<br />
Every SIVACON assembly<br />
is manufactured exclusively<br />
from standardized and<br />
series-produced modules<br />
oriented to requirements.<br />
All modules are type-tested<br />
and incorporate high quality.<br />
By virtue of a wide range of<br />
possible module combinations,<br />
justice is done to all<br />
stipulations. Adaptations to<br />
new performance demands<br />
can be realized easily and<br />
swiftly by simply replacing<br />
or adding modules. The<br />
advantages of the modular<br />
concept are obvious:<br />
• Type-testing provides proof<br />
of safety and quality for each<br />
installation<br />
• All requirement profiles are<br />
fulfilled with the high quality<br />
of standard production<br />
• Ordering of spares and<br />
additions is easy and<br />
delivery times are short<br />
SIVACON offers<br />
advantages that set<br />
new standards<br />
• Type-tested standard<br />
modules (TTA)<br />
• Space-saving base areas<br />
from only 400 x 400 mm<br />
• High packing density with<br />
up to 40 feeders per cubicle<br />

Circuit-Breaker Design –<br />
Compact, Reliable and User-Friendly<br />
Distribution boards for substantial energy requirements are<br />
generally followed by a number of subdistribution boards<br />
and loads. Particular demands are therefore made in terms<br />
of long-term reliability and safety. That is to say, "supply",<br />
"coupling" and "feeder" functions must be reliably available<br />
over long periods of time. Maintenance and testing must not<br />
involve long standstill times.<br />
SIVACON meets these requirements with circuit-breaker design<br />
components.<br />
Compact and reliable<br />
• High degree of safety by<br />
virtue of type-tested<br />
standard modules (TTA)<br />
• Test and disconnected<br />
position with door closed<br />
• Cubicle dimensions tailored<br />
to circuit-breaker sizes (e.g.<br />
1600 A with 400 mm width<br />
and 3200 A with 600 mm<br />
width)<br />
• For every rated current<br />
range, optimum connection<br />
conditions for cables and<br />
busbars<br />
• Separate function<br />
compartments consisting<br />
of a switching device<br />
compartment, an auxiliary<br />
equipment compartment<br />
and a cable or bar<br />
connection compartment<br />
• High degree of safety for<br />
assembly personnel by<br />
virtue of cubicle separation<br />
on both sides<br />
User-friendly<br />
with Sentron WL<br />
Siemens 3WL non-withdrawable<br />
and withdrawable<br />
circuit-breakers are used for<br />
the rated current range from<br />
630 to 6300 A. This means:<br />
• Free choice of the supply<br />
direction without any<br />
sacrifices in terms of<br />
technical data<br />
• High short-time currentcarrying<br />
capacity for timegraded<br />
short-circuit<br />
protection (up to 400 ms)<br />
assures reliable operation<br />
of sections of the switchboard<br />
not affected by a<br />
short circuit<br />
• Short-circuit protection with<br />
short-time grading control<br />
(zss) for very brief delay<br />
times (50 ms)<br />
• LCD operating current<br />
indication in the control<br />
console (without ammeters<br />
and current transformers)<br />
• Indication and operation<br />
when the door is closed<br />

Withdrawable Unit Design –<br />
Ergonomic, Reliable and Versatile<br />
Whether in power plants, industrial installations<br />
or office complexes, an adequate amount of<br />
energy must be available at the necessary<br />
location and at all times. However, requirements<br />
frequently change. For example, motor power<br />
ratings change or new loads have to be<br />
connected.<br />
SIVACON's withdrawable unit design offers the<br />
required degree of power supply flexibility.<br />
What's more, it was conceived on the basis of<br />
ergonomic criteria. Easy handling and short<br />
conversion times assure high availability of the<br />
system.<br />

and are connected by means of crossbars to obtain<br />
the dimensionally accurate and sturdy SIVACON<br />
frame.<br />
• All necessary cutouts for<br />
the switchboard are<br />
integrated in the side walls,<br />
ensuring a high degree of<br />
safety by way of only a few<br />
parts<br />
• The use of galvanized<br />
sheets assures long-term<br />
corrosion protection and<br />
absolutely safe earthing<br />
• Powder-coating of the<br />
visible enclosure largely<br />
prevents damage during<br />
transport, assembly and<br />
operation<br />
• Detachable frame and<br />
enclosure parts enable<br />
subsequent assembly of<br />
the horizontal busbars<br />
• Without the need for<br />
additional partitions, the<br />
part-integrating solid wall<br />
design offers safety from<br />
one cubicle to another<br />
• Securing systems enable<br />
subsequent upgrading with<br />
expansion components<br />
• Spring-loaded locks reliably<br />
prevent doors from<br />
springing open<br />
unintentionally. They also<br />
ensure safe pressure<br />
equalization in the event of<br />
an arcing fault<br />
• The switchboard is capable<br />
of withstanding very high<br />
seismic stress<br />

SIVACON is resistant<br />
to internal arcing faults<br />
10<br />
Testing of low voltage switchboards under internal<br />
arcing fault conditions is classified as a special<br />
test in accordance with IEC 61641 or VDE 0660<br />
Part 500, supplement 2.<br />
This test serves to gauge the dangers to which<br />
persons might be exposed in the event of an internal<br />
arcing fault.<br />
By way of the test under internal arcing fault<br />
conditions, SIVACON provides evidence of personnel<br />
safety in terms of the following assessment criteria<br />
as standard:<br />
Arc barrier<br />
Assessment criteria<br />
1. Doors, covers etc. must not<br />
open<br />
2. No parts may fly off<br />
3. No holes may be burnt into<br />
the enclosure<br />
4. Indicators must not ignite<br />
5. The protective conductor<br />
circuit for touchable parts<br />
of the enclosure must still<br />
be in working order<br />
Additional modules for limiting<br />
the effects of the arcing fault<br />
inside the switchboard<br />
• Restriction to one cubicle<br />
(Arc barrier)<br />
• Restriction to the function<br />
compartment or place of<br />
origin<br />
• Insulated main busbars<br />

1Type-Tested Switchgear and<br />
1Controlgear Assembly (TTA)<br />
SIVACON is a type-tested switchgear and<br />
controlgear assembly (TTA) whose physical<br />
characteristics were designed in the test<br />
laboratory both for normal operating conditions<br />
and for fault situations. Conclusive<br />
type tests assure a maximum of reliability<br />
and safety. SIVACON has passed the<br />
following verification tests as detailed in<br />
IEC 60439-1 and DIN EN 60439-1<br />
(VDE 0660 Part 500):<br />
• Verification of temperaturerise<br />
limits by test<br />
• Verification of dielectric<br />
properties by test<br />
• Verification of the shortcircuit<br />
withstand strength<br />
by test<br />
• Verification of the effective<br />
connection between the<br />
exposed conductive parts<br />
of the assembly and the<br />
protective circuit by<br />
inspection or by resistance<br />
measurement<br />
• Verification of the shortcircuit<br />
withstand strength of<br />
the protective circuit by test<br />
• Verification of clearances<br />
and creepage distances<br />
• Verification of mechanical<br />
operation<br />
• Verification of the degree of<br />
protection<br />
Every SIVACON switchboard<br />
assembly undergoes routine<br />
testing before delivery:<br />
• Inspection of the assembly<br />
including inspection of<br />
wiring and, if necessary,<br />
electrical operation test<br />
• Dielectric test<br />
• Checking of protective<br />
measures and of the<br />
electrical continuity of the<br />
protective circuits<br />
These safety requirements<br />
are met by a series of details<br />
in SIVACON, for example:<br />
• With the use of the<br />
withdrawable design,<br />
operating errors are ruled<br />
out by exactly shaped<br />
mechanical guides and<br />
interlocks<br />
• Use is made of only a few,<br />
exclusively high-grade<br />
insulating materials<br />
(e.g. for rail mounts and<br />
reinforcements, etc.)<br />
• Use of reliable Siemens<br />
switchgear reduces the risk<br />
of premature failures<br />
• Reliable disconnection after<br />
70 to 100 ms even in the<br />
event of long delay times by<br />
3WN circuit-breakers with<br />
short-time grading control<br />
• Computer-assisted project<br />
planning assures error-free<br />
selection and placement of<br />
items<br />
• Arcing fault-tested<br />
• Quality management<br />
system to DIN EN ISO 9001<br />
• Environmental management<br />
system to<br />
DIN EN ISO 14001<br />
