VS1-12 side mounted indoor high-voltage vacuum circuit breaker
ZN63 (VS1) - 12G series side mounted solid sealed high-voltage vacuum circuit breaker is an indoor high-voltage switchgear, which is applicable to the three-phase power system with rated voltage of 12kV and frequency of 50Hz. It is used as a protection and control appliance. Due to the special advantages of the vacuum circuit breaker, it is especially suitable for the places where the rated current is required to operate frequently or the short-circuit current is cut off for many times. The ZN63 (VS1) - 12G series side mounted solid sealed high-voltage vacuum circuit breaker is of fixed installation, mainly used for fixed switchgear. The circuit breaker can be used independently, as well as for ring network power supply, box type transformer or various non-standard power supply systems.

VS1 indoor high-voltage vacuum circuit breaker
ZN63 (VS1) - 12 series indoor fixed high-voltage vacuum circuit breaker is a three-phase AC 50Hz indoor switchgear with a rated voltage of 12kV, which 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 operations. 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 integral fixed pole can be used in 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 mid mounted handcart switch cabinets, and the fixed type can also be used with XGN series fixed switch cabinets.
