3ah3 Vacuum Circuit Breaker Suppliers – ZN63[VS1]-12 Indoor High Voltage Handcart Vacuum Circuit Breaker – Timetric Detail:

ZN63(VS1)-12 indoor high voltage side_mounted vacuum circuit breaker is suitable for power system with 50hz

General

ZN63(VSl)-12 indoor high voltage handcart vacuum circuit breaker is applied to 12KV, three-phase, AC50Hz.It can provide control and protection for industrial and mining enterprises, power plants and substations, electrical facilities, and is suitable for frequent operation.The operating mechanism is integrated wih the circuit breaker, and the design can be used as a fixed installation unit. It can also be a special propulsion mechanism to form a handcart unit. The main loop adopts the integral solid pole to realize the miniaturization, high reliability and free-maintenance of the circuit breaker.It can be used in KYN28A-12(GZS) and other center-mounted handcart switchgears.The fixed type could also be used in the XGN series fixed switchgear.
