Highest level of performance in a compact space!

The circuit-breakers NZM1 and NZM2 can be loaded with up to 160 A/300 A rated current and safely switch off short-circuit currents up to 150 kA even with their narrowest design.

Ideas for greater performance – the contact system, for example

Innovative switching technology with a double-break contact system speeds up the switching process. In the event of a short circuit, the special shape and materials selected produce repelling magnet power that pushes the contacts apart in a fraction of a sine wave. Switching capacities up to 150 kA and operational voltages up to 690 V can be managed without difficulty. The simultaneous reduction in heat dissipation creates benefits for use in control panels.
