High power switch MOELLER
6300 A

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.
