Question

what is circuit breaker​

Answer 1

Answer:

A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected.

Answer 2

Explanation:

Circuit Breaker :

• A Circuit breaker is an automatically operated electrical switch that essentially serves the same function as a fuse.

• However, unlike a fuse, which melts when the current exceeds the particular value and then must be replaced, a circuit breaker can be reset to function again.

• Also, while a fuse makes use of the heating effect of a current, a circuit breaker makes use of the magnetic effect of a current.

• The main part of the circuit breaker is the solenoid .

• When the current in the air exceeds the prescribed limit, the core of the solenoid gets pulled into the solenoid and hits the switch, which opens and breaks the circuit.

• The switch can be turned on manually after the fault in the circuit has been repaired.
