Special features
Instantaneous shut-off of the NZM circuit breaker when the control voltage drops below 35 - 70% UsFor use with emergency-stop devices in connection with an emergency-stop buttonFor signalizing commands or different states of the circuit-breakerTwo relays per unitThe activation criteria can be configured in the trip unitConfiguration via communication, circuit breaker display, front USB port and Eaton Power Xpert Protection ManagerWhen the under-voltage trip is switched off, accidental contact with the circuit breaker’s primary contacts is prevented when switched onOnly for use with circuit-breakers with electronic tripsUnder-voltage trip relay modules cannot be installed simultaneously with make-before-break auxiliary contact NZM...-XHIV, under-voltage trip NZM...-XU... or shunt trip NZM...-XAPush-in clamp relay contacts for control wiringRelays can be used for controlling remote operator with Us=208-204 V ACCannot be used with the PXR10 NZM-AX electronic trip
