The vacuum circuit breakers are mainly used in medium voltage applications, where the supply voltage ranges from 11 kV to 33 kV. In the VCB, the contacts of the circuit breaker are enclosed in a completely sealed vacuum cylinder. When the contacts are separated due to vacuum between the contacts, no arc is produced.
12KV MV VCB outdoor high voltage vacuum circuit breaker with controller As the power grid's breaking switch, it can realize the distribution network automation after installation of the controller. basic functions such as breaking and closing load current, overload current and short circuit current.
