Description

VS1 vacuum circuit breaker(VCB) with insulated cylinder

Description:
VS1-12 series of indoor vacuum breaker with common insulated cylinder is three-phrase A.C. 50 Hz indoor power distribution equipment with the rated voltage of 12KV. It’ s used for protecting controlling the electrical equipment in the fields of industry and mining enterprise, power plants and substation.This type vacuum circuit breaker conforms to national standards and the stipulation of IEC standard, the capability reaches grade of M2-E2-C2.
The product adopts composite insulation way,spring charged operation and rod push mechanism,with the characteristics of small volume, compact design and reliable operation. It can easily match with the switchgear and meet the “Five Preventions” demands.
This kind of vacuum circuit breaker can be used for many kinds of switchgear like KYN28(GZS1). This series of products include:VCB truck isolation truck and Fuse truck, etc.
