Special features

For interlocking and load-shedding circuits, as well as for early-make of the undervoltage release in main-switch applications.

Instantaneous shut-off of the NZM circuit breaker when the control voltage drops below 35 - 70% Us.

For use with emergency-stop devices in connection with an emergency-stop button.

When the under-voltage trip is switched off, accidental contact with the circuit breaker’s primary contacts is prevented when switched on.

Early-make of auxiliary contacts on switching on and off (manual operation): approx. 20 ms (NZM2/3) and 90 ms (NZM4).

Undervoltage release modules cannot be installed simultaneously with early-make contact NZM…-XHIV, shunt release NZM…-XA… or relais modules NZM...-X2A...
