What Are The Main Functions Of Circuit Breakers

The function of circuit breaker one
Circuit breakers, also known as air switches, are used to cut off and connect load circuits, as well as cut off faulty circuits, to prevent accidents from escalating and ensure safe operation. In case of overload or abnormal operation of electrical appliances, if a fault occurs, the circuit breaker will automatically disconnect the switch, playing a role in protecting the electrical appliances and circuits; In addition, the circuit breaker is equipped with a leakage protection device, which has the function of leakage protection.

The function of circuit breaker two
Circuit breakers can be used to distribute electrical energy, infrequently start asynchronous motors, protect power lines and motors, etc. When they encounter serious overload, short circuit, and undervoltage faults, the circuit breaker can automatically cut off the circuit. Its function is equivalent to a combination of fuse type switches and overcurrent/undervoltage relays, and generally does not need to change components after breaking the fault current.
