Circuit-Breakers and Switch-Disconnectors up to 6300 A
Intelligent and capable of communication
The IZM was the realisation of an idea for air-break circuit-breakers which has now become the standard worldwide. The compact circuit-breaker in the rated current range 630 to 6300 A utilises the very latest protective measures from the field of panel building – new technology which, in many respects, has set new standards: in terms of performance with higher switching capacities; in terms of function through the increased signalling and information features; and in terms of handling through front access to the operating components and in terms of installation through the identical connection positions for fixed or withdrawable installation.
The IZM is available in three frame sizes up to 6300 A. The new compact frame size 1 from 630 A to 1600 A only requires a 400 mm wide area in the control panel – and that saves space. Frame size 2 covers the wide range from 800 – 3200 A, simplifying both engineering and handling. The new frame size 3 up to 6300 A is even more compact and now has its operating panel situated in the centre. The same door cutout fits all breaker sizes.
Accessories and auxiliary equipment are identical for the entire range, thus enabling retrofitting to be carried out on site for all versions. Each size of IZM is also available as an IN switch-disconnector. Both accessories and operation are identical to those of the IZM circuit-breaker.
The IZM: Crammed with good ideas.

Application
FEAS semiconductor contactor of the series HR3. 3-polige is electronic load relays, which scolded to the loudless with high switching frequencies in 3-Phasen alternating voltage systems are used. By contactless scolded is almost unlimited the life span. The robust power semiconductors scolded in tension zero crossover and produce so no additional high frequency malfunctions. The equipment is integrated into a functional and sturdy housing, which makes it insensitive to shock demand and vibrations. Also an employment in aggresiver pollutant environment is unproblematic.
An inserted temperature monitoring signals an excessively high temperature rise before the equipment protects themselves and switches off. The integrated phase failure monitoring prevents a starting of the engine in case of failure a phase.
Temperature rise and phase failure are indicated in each case by relay contact.
Operational principle
The semiconductor relay HR 3.2.230.20 - 400 works according to the principle of a zero crossover or a zero voltage switch. After the creation of the control voltage scolded the power output (load circuit) of the semiconductor relay with the first zero-run of the mains voltage.
The typical response time is smaller than the half period duration and amounts to with 50Hz less than 10mS. Due to their excellent behavior with current peaks and reverse voltages these semiconductor relays are particularly suitable for applications with inductive and capacitive loads.
Execution
Inserted and completely poured in an aluminum housing for the direct assembly on DIN rail.
