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.
