Product Description

VS1-12 Vacuum Circuit Breaker

        The ZN63 (VS1) -12 series indoor fixed/handcart type high-voltage vacuum circuit breaker is a three-phase AC 50Hz indoor switchgear with a rated voltage of 12kV. It can be used for control and protection of industrial and mining enterprises, power plants and substations, electrical facilities, and is suitable for frequent operation places. By integrating the operating mechanism with the circuit breaker body, it can be designed as a fixed installation unit or equipped with a dedicated propulsion mechanism to form a handcart unit for use.

         The main circuit can be equipped with integral fixed pole to achieve miniaturization, high reliability, and maintenance free of circuit breakers. It can be used with KYN28A-12 (GZS) and other mid mounted handcart type switchgear, and can also be used with XGN series fixed switchgear.
