Product Description

12kv Medium Voltage Vcb 630A-5000A Fixed Type Vacuum Circuit Breaker
"Vacuum circuit breaker" is named after its interrupting medium and the insulation medium of the contact gap after interrupting is high vacuum; it has the advantages of small size, light weight, suitable for frequent operation and interrupting without maintenance, and is more popularly used in the distribution network. The vacuum circuit breaker is an indoor power distribution device in 3~10kV, 50Hz three-phase AC system, which can be used for protection and control of electrical equipment in industrial and mining enterprises, power plants and substations, and is especially suitable for use in places requiring oil-free, less maintenance and frequent operation, and the circuit breaker can be configured in middle cabinets, double cabinets and fixed cabinets for control and protection of high-voltage electrical equipment.

 

Model VS1 series of circuit breakers assembly are mainly used in the rated voltage12-24kv, the rated short circuit breaking current 20 and 50KA, and the rated current 630-5000A for the power distribution users.

The mechanical endurance is 20000 operating and 50 operating full capacity breaking ability at small current. It is suitable for the application with frequent operation and it features free of maintenance and few service.It could be used with Model KYN28A(GZS1) metal-enclosed switchgear and other fixed cabinet or handcart cabinet.
