NZM circuit-breakers  

These circuit-breakers protect electrical equipment against thermal overloading and short circuits. They cover the rated current range from 20 to 1600 A.

Depending on the version, they have additional protective functions such as fault-current protection, earth-fault protection or the capability for energy management by recognition of load peaks, and deliberate load shedding.

Circuit-breakers NZM are distinguished by their compact shape and their current-limiting characteristics.

Switch-disconnectors without overload or tripping units are available in the same sizes as the circuit-breakers and can be fitted with additional shunt or undervoltage releases to suit the respective versions.

Circuit-breakers NZM and switch-disconnectors are built and tested according to standard IEC/EN 60947.

They feature isolating characteristics. In conjunction with a locking device, they are suitable for use as main switches according to IEC/EN 60204/VDE 0113, part 1.

The electronic releases of frame sizes NZM2, NZM3 and NZM4 feature communication capabilities.

The current states of the circuit-breaker on site can be visualized via a Data Management Interface (DMI) or via digital output signals. Additionally, the circuit-breakers can be connected to a network, e.g.
