SUMMARY
ZN63(VS1)-12 indoor high voltage handcart vacuum circuit breaker is applied to 12Kv,three-
phase,Ac 50Hz . lt 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 with the circuit breaker and the design can be used as a fixed installation unit. lt can also be a
special propulsion mechanism to forma handcart unit.The main loop adopts the integral solid pole to
realize the miniaturization, high reliability and free maintenance of the circuit breaker, lt can be used in
KYN28A-12 (GZS) and other center-mounted handcar switchgears. the fixed type could also be used in
the XGN series fixed switchgear.
