A circuit breaker is a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The function of the circuit breaker is to cut off and connect the load circuit and cut off the fault circuit.

Outdoor circuit breakers are switches for outdoor power transmission and distribution lines. The vacuum circuit breaker is named for its arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing are both high vacuum. Vacuum outdoor circuit breakers are used to open and close power transmission circuits. They are suitable for frequent outdoor operations and have the advantages of arc extinguishing without maintenance. They are widely used in distribution networks.
