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.
ZW32-12 Outdoor AC Vacuum Circuit Breaker is used to make and break load current, overload current and short-circuit current in 12/24kV, 50/Hz power system. It is applicable for substations, industry and mining, urban and rural electricity power networks, especially for occasions of frequent operation and automatic power distribution network.
It accords with the standard of IEC62271-100&GB1984:AC high voltage circuit breaker, IEC60694&GB/T11022:HV General technical requirement of switch and control apparatus.
