The outdoor AC vacuum circuit breaker is s used in three-phase power system of AC 50Hz, rated voltage 10kV to 12kV, as breaking, making load current. Also, the circuit breaker has the function of overload and short circuit protection, controlling, measuring, remote control and remote monitoring. It accords with the standards of IEC62271-100 & GB1984 AC high voltage circuit breaker, GB/T 11022 HV General technical requirement of switch and control apparatus.

Vacuum circuit breakers are well suited for the duties that a circuit breaker must perform. A vacuum circuit breaker is a quiet, fast and efficient circuit breaker. The long operating life and low maintenance of vacuum switches has already been proven to be a fact. These attributes, and the absence of any exhaust, make them ideally suited for such highly repetitive switching operations, especially under hazardous conditions.
