Working Mechanism

  • The working of these miniature circuit breakers is based on the thermal-magnetic principle, wherein two main elements (thermal and magnetic) work together to detect overcurrents and trip.
  • As the breaker trips, the main contacts open and disconnect the circuit to avoid any damage.

Frequently Asked Questions

What is the difference between a thermal and a magnetic element?

  • The thermal element is designed to respond to steady-state overcurrents and is represented by a 'C-curve' on the graph. The element will heat up as the current increases. As the current exceeds the rated temperature, the element will cause the breaker to trip.
  • The magnetic element responds to high inrush current & is represented by a 'D-curve'. The magnetic element will generate a force as the current increases and cause the breaker to trip when the current reaches a certain level.

How do I reset my circuit breaker after it trips?

Users can reset this breaker by pushing the button or turning the handle to the 'ON' position to start the current flow in the circuit.

What is meant by the C-curve on a graph?

A C-curve is defined as the relationship between the current flowing through the breaker and the time it takes for the breaker to trip.
