Product Description

Product Description

10KV VS1 High Voltage vacuum circuit breaker Car type VCB

VS1(ZN63A)-12 type indoor high-voltage vacuum circuit breaker, a three-phase AC 50Hz rated voltage of 12KV power system indoor switching equipment, as the power grid equipment, industrial and mining enterprises power equipment protection and control unit. It is suitable for frequent operation at the rated working current, or where the short circuit current is broken multiple times.

The circuit breaker adopts the integrated design of operating mechanism and circuit breaker body. It can be used as a fixed installation unit, and it can also be equipped with a propulsion mechanism to form a handcart unit.
