Tips: What is Vacuum Ciucuit Breaker?
“Vacuum circuit breaker” is named because its arc extinguishing medium and the insulation medium of contact clearance after arc extinguishing are high vacuum. It has the advantages of small volume, light weight, suitable for frequent operation, arc extinguishing without maintenance, and is widely used in distribution networks. Vacuum circuit breaker is an indoor power distribution device in 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 no oil, less maintenance and frequent operation. Circuit breakers can be configured in central cabinets, double cabinets and fixed cabinets for control and protection of high voltage electrical equipment.
