Undervoltage release
Undervoltage release with early-make auxiliary contact
|
Special features |
Undervoltage release with 2 early-make auxiliary contacts, e.g., for early-make connection of undervoltage release in main switch applications, as well as for interlock and load shedding circuits.
For use with emergency-stop devices in connection with an emergency-stop button.
If the shunt trip is live, 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
Cannot be used in conjunction with NZM...-XR... remote operator.
Undervoltage releases cannot be installed simultaneously with NZM...-XHIV... early-make auxiliary contact or NZM...-XA... shunt release.
