CIRCUIT BREAKER

The circuit breaker can open and close the load circuit, and can also protect the electrical equipment from being damaged by overload or overcurrent. According to the scope of application, circuit breakers can be divided into high-voltage circuit breakers and low-voltage circuit breakers. High-voltage circuit breakers are mainly used for electric energy distribution of large outdoor electrical equipment, and their voltage is generally above 3KV. Low-voltage circuit breakers are mainly used for electric energy distribution of small indoor electrical equipment, and their voltage is generally within 1KV.

The short-circuit protection function of the circuit breaker is relized by the electromagnetic release; and the short-circuit protection function of the circuit breaker is relized by the undervoltage release. Compared with fuse protectors, circuit breakers are not disposable devices. When the circuit is seriously overloaded, short-circuited, under-voltage or other faults, the circuit breaker will automatically cut off the circuit; when the circuit is normal, simply reset the circuit breaker to restore it to normal operation.
