Special features
  • Instantaneous shut-off of the NZM circuit breaker when the control voltage drops below 35 - 70% Us
  • For use with emergency-stop devices in connection with an emergency-stop button
  • 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, circuit breaker display, front USB port and Eaton Power Xpert Protection Manager
  • When the under-voltage trip is switched off, accidental contact with the circuit breaker’s primary contacts is prevented when switched on
  • Only for use with circuit-breakers with electronic trips
