VS1-24kV Indoor High Voltage vacuum circuit breaker with embedded pole

Description:

VS1-24 series of indoor high voltage vacuum circuit breaker with embedded poles is three phrase A.C.50 Hz indoor power distribution equipment with the rated voltage of 24 KV. It’s used for protecting and controlling the electrical equipment in the fields of industry and mining enterprise, power plants and substation.

The main conductive circuit of this type vacuum circuit breaker with spring mechanism is embedded pole,that can greatly improve the reliability of insulation, mechanical and breaking performance and really realize the free-maintenance and longer mechanical and electrical life.This type vacuum circuit breaker conforms to national standards and the stipulations of IEC standard. The capability reaches grade of M-E2-C2.

The product is used for many kinds of switchgear like KYN28-24(GZS1) and can be fixed installation.
