DescriptionNon-delayed disconnection of NZM circuit-breaker or N switch-disconnector when the control voltage sinks 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.

Undervoltage releases cannot be installed simultaneously with NZM…-XHIV… early-make auxiliary contact or NZM…-XA… shunt release.
