Product Description

FZ(R)N21-12D AC high voltage vacuum load breaking switch
FZN21-12D/T630-20 series three poles alternating current vacuum load break switch-fuse protector combination. It has merit of excellent breaking ability, small size, long electric life, free of maintenance, can break rated current, overload current (FZN21-12D/T125-31.5 can break short circuit current) and prevent device from phase-default operation. The switch has an obvious visible isolate fracture to assemble earth switch and electric spring mechanism, thus can conduct remote control.
Ambient condition
1 Ambient temperature: max +40°C min -15°C(conveyance under -30°C is allowed)
2 Altitude: ≤1000m
3 Relative humidity: daily average relative humidity: ≤95%; monthly average relative humidity≤90%; daily average saturated vapor pressure ≤2.2*10-3 MPa; monthly average value  ≤1.8*10-3 MPa
4 Earthquake intensity: ≤8 degree
5 The installation should be free from fire, explosion, severe vibration, chemical corrosion and serious pollution
