|Accessories|||Undervoltage release with early-make auxiliary contact|
|Standard/Approval|||UL/CSA, IEC|
|Construction size|||NZM2/3|
|Description|||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.
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
Undervoltage releases cannot be installed simultaneously with NZM...-XHIV...
early-make auxiliary contact or NZM...-XA... shunt release.
Cannot be used in conjunction with NZM...-XR... remote operator.|
