Product Description
HV Circuit Breaker
1 General state
The 8-12 ZW type outdoor vacuum circuit breaker of high voltage ( following abbreviation circuit breaker) can divide into used in the three-phase power system of 50 alternating Hz-12 kVs the load current that joins circuit, overload current and the fault current of short circuit, the room control of electrical network is protected equipment after circuit breaker and switch-disconnector are made up ( following abbreviation combination circuit breaker), page may use as section switch.
HV Circuit Breaker
