VS1-12 series indoor high voltage vacuum circuit breaker is an indoor switchgear with three-phase AC 50Hz 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 integrated design of the operating mechanism and the circuit breaker body is adopted. The integral fixed sealing pole can be adopted for the main circuit 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.
