Product Description

Specifications

1.rated voltage 12KV 
2.FK(R)N12-12 high voltage load switch 
3.suitable to three phase AC 5HZ power distribution system 

FKN12-12 load braek switch

Introduction: 

1.FK(R)N12A-12D compressed-air load switch- fuse protector combination unit is used in the 3 phase power distribution system with rated voltage up to12KV. 

2.Being the control and protection unit of ring-net, double radiation power supply unit and electrical equipments such as transformer, electrical cable, it's especially suitable to city and rural substation and box type substation. 

3.FKN12-12D compressed-air load switch can open and close the load current and overload current, as well as can open and close the load current, overload current and the breaking short-circuit current.

  

Operating environmental conditions:

1.Altitude: ≤1000m

2.ambient air temperature: not higher than +40°C,not lower than-25°C

3.Relative humidity: daily mean is not more than 95%, monthly mean is not more than 90%

4.Earthquake intensity: not more than 8°

5.no fire, explosion hazard, chemical etching and intense vibration

6.Pollution grade: II

7. Ambient air shouldn't be polluted by corrosive or flammable gas and vapor.
