ZN63 VS1 Indoor high voltage vacuum circuit breaker produced by Kexun, a well-known manufacturer in China, is suitable for electrical equipment with rated voltage of 12KV and three-phase AC of 50hz, and is often used for control and protection of industrial and mining enterprises, power plants, substations and electrical facilities.
Design feature
ZN63 VS1 Indoor high voltage vacuum circuit breaker adopts the integration of VET operating mechanism and circuit breaker body, which can be designed as a fixed installation unit or a handcart unit with a special propulsion mechanism. The main circuit part can adopt integral sealed pole to realize miniaturization, high reliability and maintenance-free of the circuit breaker. It can be used with KYN28A-12(GZS) and other central handcart switchgear, and can also be used with XGN fixed switchgear.
Using conditions
.Ambient temperature: ZN63 VS1 Indoor high voltage vacuum circuit breaker should be operated at -10~40ºC (storage and transportation at -30ºC is allowed).
Altitude: ZN63 VS1 Indoor high voltage vacuum circuit breaker should be installed at an altitude of less than 1000m.
Relative humidity: the daily average value is not more than 95%, the daily average value of saturated vapor pressure is not more than 2.2x10-MPa, and the monthly average value is not more than 1.8x10-MPa
Note:ZN63 VS1 Indoor high voltage vacuum circuit breaker shall work in a place without fire, explosion, serious pollution, chemical corrosion and violent vibration.
Meet the standard
IEC60265,IEC62271,GB3804,GB16926 etc..
