Vacuum Circuit Breakers 

Power distribution arena has been one of the strongholds for CG Medium Voltage (MV) Switchgear Division since its inception in 1985. We pioneered the arrival of vacuum technology in India with vacuum interrupters.

CG is the largest manufacturer of indoor vacuum circuit breakers (VCB) as well as outdoor porcelain clad VCBs in India. We also offer outdoor metal clad VCBs (KIOSK).

Besides, we offer economical retrofitting solutions for upgrading BOCB to VCB technology by interchanging the BOCB truck with a VCB truck in the existing panel. There is no need to modify the associated relays, current transformer / potential transformer, busbar chamber and instrument cubicle on the existing panel.
