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 switching off devices in conjunction with Emergency switching off button.
When the undervoltage release is de-energized, accidental contact with the main contacts of the switch during attempts to switch on is safely prevented.
Early-make of auxiliary contacts on switching on (manual operation): approx. 90 ms.
Undervoltage releases cannot be installed simultaneously with NZM...-XHIV... early-make auxiliary contact or NZM...-XA... shunt release.
