Outdoor high voltage Vacuum Circuit Breaker is the outdoor power distribution equipment of rated voltage 12kV, 24kV, 40.5kV, three-phase AC 50/60HZ. They are designed for the construction and reform of urban and rural grid.

The breaker is mainly used in load current, overload current and short circuit current of power distribution lines opening and closing of electric power system. It applies to distribution system of power plants and substations, industrial and mining enterprises to control and protect the downstream equipment.

Indoor high voltage vacuum circuit breakers is applied to three phase AC50HZ indoor power distribution equipment with the rated voltage of 12kV, 24kV, 40.5kV. It’ s used for protecting and controlling the electrical equipment in the fields of industry and mining enterprise, power plants and substation, specially for the important high altitude breaking load and frequent operation place.
