High voltage Vacuum circuit breaker is an indoor power distribution device in the 3~10kV, 50Hz three-phase AC system, which can be used for the protection and control of electrical equipment in industrial and mining enterprises, power plants, and substations. It is especially suitable for places requiring oil-free, less maintenance and frequent operation. The circuit breaker can be configured in the central cabinet, double-layer cabinet, and fixed cabinet to control and protect high-voltage electrical equipment.
Specifications:
1.Vacuum Circuit Breakers can usually be divided into several voltage levels. Low-voltage type is generally used for explosion-proof electrical use. Like coal mines and so on.
2.The rated current reaches 5000A, the breaking current reaches 50kA, and the voltage has reached 35kV.
