The application in the network is more popular. Vacuum circuit breaker is an indoor power distribution device in a 3~10kV, 50Hz three-phase AC system, which can be used as the protection and control of electrical equipment in industrial and mining enterprises, power plants, and substations. It is especially suitable for For places requiring oil-free, less maintenance and frequent operation, circuit breakers can be configured in middle cabinets, double-layer cabinets, and fixed cabinets to control and protect high-voltage electrical equipment. Performance characteristics:1.Small contact distance2.Short arcing time3.After the arc is extinguished, the recovery speed of the contact gap medium is fast and good.4.Low noise, suitable for frequent operation.5.Small size and light weight.6.Suitable for breaking capacitive load current.
