Under the power supply of 12kV, three phase AC 50/60Hz, the ZW53-12 outdoor AC high voltage vacuum circuit breaker is used to make and break all the currents within the scope from load current, overload current to short-circuit current.
This product is extensively applied in the substations, industry and mining, urban and rural electricity power networks. Moreover, it is in strict consistence with the international IEC62271-100 and GB1984 standard about the AC high voltage circuit breaker, as well as the GB/T 11022 Common Specification for High Voltage Switchgear and Control Gear Standard.
