It has the advantages of small size, light weight, suitable for frequent operation, and arc extinguishing without maintenance. It is widely used in distribution networks. Vacuum circuit breaker is an indoor distribution device in 3~10kV, 50Hz three-phase AC system. It can be used for protection and control of electrical equipment in industrial and mining enterprises, power plants, and substations. It is particularly suitable for places that require oil-free, less maintenance and frequent operation. The circuit breaker can be configured in a central cabinet, double-layer cabinet and fixed cabinet to control and protect high-voltage electrical equipment.
