Product Parameters

 

Zn63 (VS1) - 12 series indoor handcart type high voltage vacuum circuit breaker is an indoor switchgear with three-phase AC 5ohz and rated voltage of 12kV. It can be used for the control and protection of industrial and mining enterprises, power plants, substations and electrical facilities, and is suitable for places with frequent operation. The operating mechanism is integrated with the circuit breaker body, which can be used as a fixed installation unit or a special propulsion mechanism to form a handcart unit. The main circuit part can adopt the integral fixed sealing pole to realize the miniaturization, high reliability and maintenance free of the circuit breaker. It can be equipped with kyn28a-12 (GZS) and other middle mounted handcart type switchgear, and the fixed type can also be used for XGN series fixed switchgear.
