Basic Info.Model NO.ZN63(VS1)E-12KVBreaking CapacityHigh Voltage Circuit BreakersOperationElectric TypeSpeedHigh-Speed Circuit BreakerArc-extinguishing MediumVacuumFunctionConventional Circuit BreakerProduct DescriptionoverviewThe ZN63 (VS) E-12kV series solid sealed high-voltage vacuum circuit breaker is suitable for three-phase AC power systems with rated voltage of 7.2-12kV and frequency of 50Hz. It is widely used in power plants, substations, petrochemical, metallurgical, manufacturing, airports, and residential areas. It is used for protection and control of electrical facilities, especially in places with frequent operation or multiple interruptions of short-circuit current under rated current. It can be installed in movable or fixed air insulated switchgear. The product meets the requirements of GB1984 "AC High Voltage Circuit Breakers", DL/T403 "Technical Conditions for Ordering 12-40.5kV Indoor AC High Voltage Circuit Breakers", as well as relevant standards such as IEC60694 and IEC6227-100. The ZN63 (VS) E-12kV series sealed high-voltage vacuum circuit breaker adopts advanced APG technology, directly sealing the vacuum arc extinguishing chamber and main electrical circuit inside the epoxy resin pole to form a sealed insulation method, representing the highest level of design and manufacturing for high-voltage vacuum circuit breakers in the world today.Note: When replacing the fixed sealing pole of the vacuum arc extinguishing chamber with a regular insulation cylinder for this model of product, the model is ZN63 (VS) -12.Model Description  Environmental conditions for use1.
