● Design feature
ZN63 VS1 Indoor high voltage vcb 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 vcb should be operated at -10~40℃ (storage and transportation at -30℃ is allowed).
▶ Altitude: ZN63 VS1 Indoor high voltage vcb 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 vcb shall work in a place without fire, explosion, serious pollution, chemical corrosion and violent vibration.
◆ Meet the standard
IEC60265、IEC62271、GB3804、GB16926 etc..
