Product Introduction

VS1-12 630A 1250A vacuum circuit breaker is indoor switchgear with three-phase, rated voltage of 12kV, control and protection for industrial and mining enterprises, power plants and substations, electrical facilities, and for frequent operation place adopting VET operating mechanism and circuit breaker integrated design can be used as a fixed installation unit can also be equipped with special advance mechanism, the composition of handcart unit used some of the main circuit can use the whole solid seal post with high reliability, maintenance-free, in order to achieve smaller circuit breakers, can be equipped with KYN28A 12 and other handcart switch cabinet. In the home, it can also be used with fixed XGN switchgear.

Structural features

1. This series of VCB is used for Integrated design for operating mechanism and VCB body with the reasonable, beautiful, and compact arrangement.
2. This series of VCB adapted vertical insulation house against Impact due to different weather, it can effectively prevent VIS against damage by exterior factors.
3. The two different installation units of Fixed type and withdrawable type can meet the different requirements for different switchgear.
