The function of the circuit breaker is

  • The function of a circuit breaker is to safeguard the electrical circuit by interrupting the flow of current when an overcurrent condition occurs.
  • This overcurrent condition can be caused by a short circuit, an overload, or a ground fault.
  • Circuit breakers are designed to protect electrical equipment and wiring from damage due to excessive current flow.
  • When the current exceeds the rated capacity of the circuit, the circuit breaker automatically trips and interrupts the flow of current, preventing damage to the equipment and wiring.
