Delivery program

Type
  • Accessory
  • Shunt release
Special features
  • When the shunt release is live, contact with the circuit-breaker's main contacts on switching on is reliably prevented.
  • Early-make of auxiliary contacts on switching on and off (manual operation): approx. 20 ms (NZM2/3) and 90 ms (NZM4).
  • Shunt release modules cannot be installed simultaneously with early-make contact NZM…-XHIV, untervoltage release NZM…-XU…, relais modules NZM...-X2A..., or remote operator NZM...-XR...
