Product specifications

Type
Special features
  • The breakers are actuated by a voltage pulse or by applying a no-break current.
  • For signalizing commands or different states of the circuit-breaker.
  • Two relays per unit.
  • The activation criteria can be configured in the trip unit.
  • Configuration via communication or circuit breaker display or front USB port and Eaton Power Xpert Protection Manager.
  • If the shunt trip is live, contact with the circuit breaker’s primary contacts is prevented when switched on.
  • Only for use in combination with circuit-breakers with electronic trips.
  • Shunt trip relay modules cannot be installed simultaneously with make-before-break auxiliary contact NZM...-XHIV, under-voltage trip NZM...-XU... or shunt trip NZM...-XA.
  • Relay coil is controlled by trip unit.
  • Relay contacts for control wiring.
  • Relays can be used for controlling remote operator with Us=208-204 V AC.
  • Control wiring on push-in clamps.
  • Cannot be used with the PXR10 NZM-AX electronic trip.
