VS1 Indoor Medium Voltage Fixed Vacuum Circuit Breaker, with a voltage of 24kV, is a common vacuum circuit breaker for electrical protection and control. It is suitable for places such as substation, mining and industrial enterprises, and frequent electrical operated country power net.

Product Details

General Description

VS1-12 series of indoor vacuum circuit breaker is used for indoor 12kv switchgear,it is suitable to control and protect transmission and distribution system such as electric network equipment and industrial&minning industry etc as their protection and control unit.

It can match with KYN28(GZS1),XGN and GG1-A series of switchgears.this series of products include:VCB truck,isolation truck and fuse truck etc.

1.This series of VCB is used integrated design for operating mechanism and VCB body with reasonable,beautiful and compact arrangement.

2.This series of VCB adopted vertical insulation house against impact due to different weather,it can effectively prevent VIS against damage by exterior factors.

3.With two kinds of installation unit:fixed type and withdrawable type,it can meet different assembling requirements between switchgear and breaker.
