Working Mechanism

  • The electronic trip unit uses a microprocessor to monitor the current flowing through conductors and compares it with the set current rating of the breaker.
  • When an overcurrent condition occurs, the electronic trip sends a signal to open the main contacts and interrupt the current flow.
  • As the breaker trips, the indication LED on the front of the breaker illuminates, and the trip records the event in its memory.
