Working Mechanism

  • These circuit breakers come equipped with an electronic trip unit that uses microprocessors to monitor the current flowing through conductors.
  • When an overcurrent condition is detected, the electronic trip sends a signal to the breaker's operating mechanism to open the main contacts and interrupt the current flow.
  • When the breaker trips, the indication LED on the front of the breaker illuminates and the trip records the event in its memory.
  • Users can adjust the trip settings to accommodate different load types and provide instant protection against specific faults, such as ground faults.

Frequently Asked Questions

How to reset the tripped circuit breaker?

After an automatic or accessory-initiated trip or a manual push-to-trip operation, the breaker can be reset by pressing the reset button on the front of the breaker, clearing the trip indication LED and resetting the breaker's memory.

What is the function of the push-to-trip button on MCCBs?

A push-to-trip button is a manual override feature that allows the operator to manually trip the breaker and interrupt the current flow. This feature is used for testing or emergency situations when the breaker needs to be tripped manually.

What are different trip settings available for these electronic circuit breakers?

  • Long Time: These trips will wait a certain amount of time to allow temporary inrush currents for passing through to aid certain applications, such as those encountered when starting a motor, before finally tripping.
  • Short time: These trips are set to trip at a current level that is lower than the normal operating current and trip quickly when exposed to short term overcurrent conditions.
  • Instantaneous: These trips protect against very high current levels, like short circuits.
