Undervoltage release
|
| Special features |
Non-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.
