ZN63(VS1-12)-12 side mounted indoor high-voltage vacuum circuit breaker, suitable for rated voltage 12kV, frequency 50Hz three-phase power system, as a protection and control appliances used, due to the special advantages of the vacuum circuit breaker, especially suitable for frequent operation of rated current, or multiple times to break the short-circuit current.

ZN85-40.5 series indoor high-voltage vacuum circuit breaker (hereinafter referred to as circuit breaker), suitable for three-phase AC 50Hz, rated voltage of 40.5kW power system, for industrial and mining enterprises, power plants and substations as the division of load current, overload current, fault current. The circuit breaker and the operating mechanism are arranged up and down, which effectively reduces the depth of the circuit breaker.

ZN63(VS1)-12 series indoor fixed/mobile high voltage vacuum circuit breaker is a three-phase AC 50Hz, rated voltage of 12kV indoor switchgear, for industrial and mining enterprises, power plants and substations, electrical facilities control and protection, and suitable for frequent operation of the place. Using the operating mechanism and circuit breaker body integration, the design can be used as a fixed installation unit, and can also be equipped with a special propulsion mechanism to form a handcart unit. The main circuit part can be used as a whole solid seal pole to achieve circuit breaker miniaturization, high reliability, maintenance-free, can be equipped with KYN28A 12(GZS) and other central hand-mounted switchgear, fixed type can also be used for XGN series fixed switchgear.
