Outdoor AC vacuum circuit breaker is used to make and break load current, overload current and short-circuit current in 12kV,50/60Hz power system. It's applicable for substations, industry and mining, urban and rural electricity power networks, especially applicable in occasions with frequent operation and automatic power distribution network. It accords with the standards of IEC62271-100 &GB1984 AC high voltage circuit breaker, GB/T11022 HV General technical requirement of switches and control apparatus.
