Description 




IZM, IN 

Moeller HPL0211-2007/2008 


IZM circuit-breakers 

The IZM from Moeller embodies a concept for open circuit-breakers that exceeds the 

standard throughout the world. Based on state-of-the-art system engineering, these 

switches open up a new dimension in the rated current range from 

630 to 6300 A. They excel not only for their performance, but also for their functionality, 

especially in their communications capabilities and their ease of handling 

and installation. 

A comprehensive operator manual is supplied with each device. 

Applications 

Coupler switches: Beside the IZM circuit-breakers, IN switch-disconnectors are available. 

These are used, for example, as coupler switches between different power 

supplies. 

Main switches: You can use both IN switch-disconnectors and IZM circuit-breakers 

as mains isolating switches. When fitted with a lockable handle, all IZM circuit-breakers 

(and IN switch-disconnectors) fulfil the main switch and isolating characteristics 

according to IEC/EN 60204-1. Depending on the type of apparatus to be 

protected, the tasks of the circuit-breakers can be split into four main applications: 

• System protection 

• Motor protection 

• Transformer protection 

• Generator protection. 

These key applications make different demands on the switches, which are met with 

a range of control units. 

Switches with closing release are suitable for synchronization tasks. 

Safety and reliability 

Numerous locking features are provided or can be fitted by the user, on the one 

hand to protect the switch and system from unauthorised switching, and on the 

other for the protection of maintenance and operating personnel. 

Further safety features are: 

• Power feed from top or bottom as required 

• Standard locking facility for the withdrawable unit when the switch is removed 

• Standard locking facility for the switch in withdrawable unit to prevent removal 

• High degree of protection with IP 55 terminal cover 

• Standard with mechanical closing lockout after overload or short-circuit release 

• The operating panel cannot be removed when the switch is operational 

• Delivery including all auxiliary circuit connectors corresponding to built-in features 

including coding device to prevent mix-up of plug-connectors with fixed 

mounted breakers 

• Devices with +IZM-XCOM-DP communication interfacing feature temperature 

sensors on the built-in microswitch detection units (XBSS) and on the communication 

module. 

Standard version 

IZM circuit-breaker has the following standard equipment: 

• Electronic overcurrent releases 

• Rated current module (with the exception of IZM…-A…) 

• Mechanical ON and mechanical OFF switch 

• Manual drive for charging the spring-operated stored energy mechanism 

• Switch position indication 0 / I 

• Ready indication OK 

• Charge state display 

• Auxiliary circuit switch 2 M + 2 B 

• Horizontal main terminals on rear with fixed mounted and with withdrawable 

units up to 5000 A and on rear with vertical main terminals at 6300 A 

• With 4-pole switches the 4th pole (N) is fitted on the left and can be loaded to 

100 % 

• Display of the contact erosion of the main contacts 

• Auxiliary current plug system with screw terminals. The switch is always equipped 

with the required number of auxiliary current plugs. 

• Mechanically tripped display of the overcurrent release system 

• Mechanical reclosing lockout after trip 

• Operation manual in English 

Additional with withdrawable units: 

• Main contacts: Laminated contacts on the back plate of the withdrawable unit, 

contact pin on basic unit 

• Position display with operating console of the plug-in switch 

• Captive crank handle for switch movement with withdrawable system 

• Withdrawable unit with guide rails for simple handling 

• Locking facility for switch movement in the withdrawable unit 

• The switch cannot be moved in the withdrawable unit in the on state 

• Rated current coding between the withdrawable unit and the switch. 

Design 

The compact design of the circuit-breakers provides optimum utilization of the available 

space, allowing control panels to be equipped more efficiently. The IZM for a 

rated current up to 6300 A, for example, can be installed in am 800 mm wide control 

panel field. Switches with a rated current of 1600 A need only a 400 mm field. 

Operating panel 

The operating panel is designed to ensure that it can protrude through a cut-out in 

the door and that all operation elements and displays can be accessed when the 

control panel door is closed. The operating panels of all switches (fixed mounted/ 

withdrawable, 3/4-pole) are identical. The operating panel provides IP20 degree of 

protection.



Current range 

Moeller HPL0211-2007/2008 

The new open circuit-breaker IZM covers the entire range from 800 A … 6300 A 

with just two frame sizes. The compact frame size IZM1 extends the rated current 

range downwards to 630 A. If required, the range can be extended to 250 A by exchanging 

the rating plug. And all this with a setting range of 0.4 … 1 x In. 

Dimensions 

The IZM devices have the same height and depth across their entire current range. 

Only their device varies depending on the number of poles and the frame size. 

Connection by 

As standard, IZM circuit-breakers are fitted with horizontal connections. Optionally, 

the following connections are possible: vertical connections, connections that are 

accessible from the front and flanged connections. 

Control units 

The IZM features microprocessor-controlled control units as standard. Five different 

control units are available for selection and thus offer optimum protection for your 

system: From simple system protection with overload and short-circuit release extending 

to a digital circuit-breaker with graphic display and the option of setting up 

time-discriminating networks. 

Control circuit connections 

The built-in auxiliary switches are connected to the male connector on the switch. 

Irrespective of the mounting type, the customer connects the auxiliary power circuits 

to the control circuit plugs at the top of the circuit-breaker. The standard terminals 

are screw-type; spring-loaded terminals are optional. 

ON fixed mounting units, the control circuit plugs are fitted directly to the plug connectors 

on the switch and are coded against accidental reversal. 

To allow withdrawable units to be moved, a sliding contact module is fitted between 

switch and mounting. The sliding contact module allows a secure connection of the 

control circuit cable connectors in the “connected” and “test” positions of the 

switch. 

Modular design 

Because components are installed from the front, retrofitting accessories is especially 

quick and easy. This allows you to respond flexibly to changing requirements 

within your system. 

Communication-capability 

With their communication-capability, the IZM circuit-breakers open up new possibilities 

in power distribution. Providing and transmitting all important operational information, 

they increase system transparency and shorten the response times to 

states such as overcurrent, phase asymmetry and overvoltage. A rapid intervention 

in a process can, for example, prevent downtimes and help to schedule maintenance 

activities and therefore boost plant availability. 

Internal system bus 

The IZM universal and digital circuit-breakers contain an internal system bus as 

standard, which connects all intelligent components of the circuit-breaker. 

Through the communications interface, the information from the intelligent components 

can then be transmitted through PROFIBUS-DP, for example with the IZM- 

XCOM communication module. 

Expansion modules for the internal system bus: 

External add-on modules can be connected to the IZM circuit-breakers through the 

internal system bus without extensive additional wiring. Digital input modules and 

digital and analog output modules are available for this purpose. A further module 

implements reduced-time selectivity control between IZM circuit-breakers. 

Description 


Selection criteria for IZM circuit-breakers 

11/9 

Fundamental criteria for the selection of circuit-breakers: 

• Max. short-circuit at the point of installation of circuit-breaker I k max: this value 

determines the short-circuit breaking capacity or the short-circuit current carrying 

capacity of the circuit-breaker. It is compared with the value I cu , I cs , I cw of 

the switch and mainly determines the size of the switch a technical data. 

• Rated current I n which should flow through the respective branch circuit: this 

value may not be greater than the maximum switch rated current of the circuitbreaker. 

The rated current is defined with the IZM with the rated current module 

(exception: overcurrent release for system protection XZMA). 

• Ambient temperature of the circuit-breaker: this is generally the internal control 

panel temperature. Observe the derating table with increased ambient temperature 

a Technical data. 

• Circuit-breaker type: fixed mounted or withdrawable, 3 or 4-pole. 

• Minimum short-circuit current, which flows through the switchgear: The release 

must recognize this value as a short-circuit and may react with a trip. 

• Protection functions of the circuit-breaker: This is determined by the selection 

of the respective overcurrent release.

Communication module 


The IZM-XCOM-DP communication module enables connection of the IZM circuitbreaker 

to the PROFIBUS-DP. A PROFIBUS master can communicate with the IZM 

via the DP and DPV1 protocols for monitoring purposes. 

Maintenance information received on time (e.g. via the operating time/hours or via 

the wear and usage of the main contacts) enables the user to prevent system standstills. 

With threshold violation signals, users can take preventative measures before 

it comes to a trip. For later analysis with the IZM-XEM-PG parameter assignment 

module, the relevant data generated when a trip takes place is saved in the device 

(for example tripping current with date and time). 

Because the communication module is attached to the frame of the circuit-breaker, 

the built-in temperature sensor measures the temperature inside the control panel. 

The switch position is transmitted to PROFIBUS through three microswitches in the 

underside of the communication module (operating, test or isolated position). 

All microswitches that record information about the state of the circuit-breaker are 

installed on or connected to the breaker status sensor (BSS module) for signalling 

internal switching states. The module provides this digital information (ON, OFF, 

status of the spring energy store, availability, voltage release) on the built-in system 

bus. A further temperature sensor determines the temperature in the circuit-breaker. 

This reading is also made available through a bus line.

g Communication module IZM-XCOM-DP 

Moeller IZM...-U... and IZM...-D... circuit-breakers are open circuit-breakers with 

communication features. Extremely space-efficient, they provide all important 

switch information. 

• The circuit-breakers can be parameterized via the local interface of the XZMD(R) 

overcurrent release. All device-specific data can be shown. 

• Built-in circuit-breaker bus for communication between IZM and release, measuring 

function, switchgear signals, remote monitoring, tripping and parameterization 

• Connection of external module to the internal system bus, for example for monitoring 

(also when subsequently upgrading without additional wiring). 

• Simple connection to PROFIBUS-DP with communication module for IZM with 

universal and digital circuit-breakers 

• The IZM circuit-breakers can be incorporated in wide-area communication solutions 

based on PROFIBUS-DP. Within the system, the circuit-breakers can be parameterized 

with a programmable logic controller (PLC). All available data can be 

read. 

• Switching, controlling and data transfer through central PC 

• Data acquisition and power management through measuring function 

The internal system bus used in the circuit-breakers with communication features allows 

various external expansion modules to be connected to the data exchange process. 

The available modules include digital output modules, an analog output module, a 

digital input module and the ZSI module for reduced-time selectivity control. The digital 

output modules with relay outputs are available in a user-programmable version 

and a version programmable with a rotary coding switch. 

The power for the external expansion module is provided by the internal system bus. 

“harmonic” measuring function 

[x263A]With the data and functions provided by the measuring function, the power 

distribution can be analysed in detail. With the setpoint functions of the measuring 

functions, users can signal or record specific events in the network. In addition, extended 

protective functions can be implemented, providing additional tripping conditions 

that are not covered by the overcurrent release. 

The "harmonic" measuring function determines currents, voltages, ratings, power 

factors, energy values , frequencies, harmonic distortion, form factors and peak factors. 

The measuring function provides two additional, independent curve form memories 

and a frequency analysis up to the 29th harmonic (fast Fourier transformation, or 

FFT), which can be used for a harmonic compensation. 

Control voltage supply 

The basic functions of the electronic overcurrent release do not require auxiliary power. 

With the “Universal” and “Digital” release it is possible to use additional functions 

which necessitate a data exchange via the internal system bus. These devices 

are fitted with the internal system bus as standard. For data communications, an external 

24 V DC power supply is required, which must fulfil the following conditions: 

• Primary switched-mode power supply unit 

• 24 V DC, G 3 % 

• Rated output current: 5 A per circuit-breaker with the greatest possible number 

of external expansion modules. 

For example, you can use the Moeller switched-mode power supply unit SN4-050- 

BI7, Article no. 200034. 

Connection to control circuit connections X8:3 and X8:4 or to one of the expansion 

modules. The various components are then supplied with power through the internal 

system bus connection. 

Additional functions through the use of: 

• Communication module 

•Expansion modules 

•Measuring module 

• 4-line display or graphic display 

• Parameter assignment module 

With the 4-line display, the phase currents and the set parameters can be viewed 

without an external power supply, as soon as the load exceeds 80 A (at IZM...1(2)...) 

or 200 A (with IZM...3...) on the main circuit. 

If the parameter assignment module is used in Offline mode (i.e. without connection 

to an electronic release), it can not be supplied through the internal system bus. In

Description 

Components for communications 


ZSI module 

Moeller HPL0211-2007/2008 


Where full selectivity at low delay times is an issue even if the circuit-breakers are 

arranged in hierarchical groups, the ZSI modules have the solution. They are used to 

connect the circuit-breakers with each other. 

If a short-circuit occurs, each circuit-breaker through which short-circuit current 

flows determines whether the adjacent circuit-breaker on the next lower level is also 

affected. This allows the exact location of the short-circuit to be identified and only 

the circuit-breaker immediately upstream of the fault location is tripped. 

With the microprocessor-controlled “delayed selectivity control”, the tripping delay 

of these upstream circuit-breakers can be reduced to up to 50 ms. 

Digital output module with rotary coding switch 

This module can output 6 binary data units concerning the switching state (trip causes 

and warnings) of external switching devices (e.g. lamps, horns, klaxons) or for 

switching off further system components (e.g. frequency inverters). 

Various versions of digital output modules are available, both with and without a 

rotary coding switch. Modules with a rotary coding switch allow selection between 

two signal blocks, each with six defined assignments, and an additional response 

delay. 

The digital output modules are available as versions with opto-coupler outputs (N/ 

O contact, 150 mA) or with relay outputs (changeover contacts up to 10 A). Up to 

two modules of this type can be connected to an IZM. 

Digital output module, configurable 

For high-performance solutions, the configurable output module is available. With 

this unit, any event on the internal system bus can be switched directly on one of six 

available outputs or three of these outputs can be assigned with up to six events 

(“OR” operation). The module can be configured with the IZM-XEM-PG or IZM- 

XEM-PGE parameter assignment module (with Ethernet interface). 

As for the output modules with rotary coding switch, a relay version are available. 

Only one module of this type can be used per IZM. 

Analog output module 

The analog output module can be used in conjunction with the measuring function 

to output the following measured values of the circuit-breaker to analog indication 

devices in the control panel door: 

• I L1 , I L2 , I L3 , I N or 

• U L12 , U L23, U L31 , U L1N or 

• P L1 , P L2, P L3 , S ges or 

• c 1 , c 2 , c 3 , DI % or 

• f avg , U LLavg , P ges , c avg 

Four interfaces (4 … 20 mA/0 … 10 V) are available for this purpose. The measured 

values for output are selected with a rotary coding switch. The use of the analog 

output module removes the need for additional transducers and their conventional 

installation and wiring in the main circuit. Up to two modules of this type can be 

connected to an IZM. 

Digital input module 

With the digital input module, six additional binary signals (24 V DC) can be connected 

to the system. Alternatively, a changeover between two parameter sets (e.g. for 

motoric and regenerative operation) can be implemented quickly and easily. 

Parameter assignment module 

The IZM-XEM-PG parameter assignment module with integrated webserver allows 

access to all device information for analysis or parameterization purposes. The parameter 

assignment module is connected to the local interface of the overcurrent release 

and, acting as a Web server, makes the data available through the Hypertext 

Transfer Protocol (HTTP). With this interface, any PC – desktop, notebook or palmtop 

– with a Web browser with Java 2 Virtual Machine can become a user interface. 

The required HTTP files are included as standard. 

No additional software needs to be installed. The data is displayed in a clear tree 

structure for quick access. With the parameter assignment module, the switch parameters 

can not only be changed, but also saved for later transmission to identical 

circuit-breakers. 

Depending on the equipment level of the IZM circuit-breaker, the following values 

can be displayed: current, voltage, power, energy, c, frequency and harmonics 

as well as temperature. 

All status information for the circuit-breaker, warning and trip indications, threshold 

violations – each with date and time of occurrence, maintenance and statistical information 

(to reduce or prevent system downtimes). 

The parameter assignment module is fitted with a magnet on its back, which makes 

it ideally suited as a portable “online” parameterization and diagnostics tool. Alternatively, 

the parameter assignment module can be used to create and modify parameter 

sets offline on a notebook. A printing function allows all processes and 

settings to be documented on paper.

The following characteristics each demonstrate the largest and smallest setting 

in the respective protective area. In order to receive the complete tripping 

characteristic, the respective characteristic sections have been brought together. 

The characteristic curves indicate the behaviour of the overcurrent release when 

it has been activated by one of the currents flowing before the trip. If the 

overcurrent trip occurs directly after switch on and if the overcurrent release is 

not activated for this reason, the opening delay may extend by up to ms 

depending on the level of the overcurrent. In order to determine the total 

opening delay of the switch, about 15 ms are to be added to the shown opening 

delays for the duration of the arc. 

The curves shown apply for an ambient temperature on the switch of – 

5 … +55 °C. The release can be operated at ambient temperatures from – 

20 … +70 °C (with LCD display up to 55 °C). An extended tolerance band range 

can apply with these temperatures.
