High voltage FZ(R)N25-12D AC vacuum load break switch

FZ(R)N25-12D/T630-20 indoor high voltage three-poles vacuum load break switch is appropriate to protect and control electrical system in mining industrial enterprise, power station, transformer substation. They are mainly used to close and break load current, closed loop current, non-load transformer, cable charging current.

FZRN25-12D/T125-31.5 type 50Hz indoor alternating current load break switch -fuse protector combination have both manual and electrical operation mechanism to realize three control requirement of electric system. Assembled earth switch can bear short circuit current.

FZN25-12D,FZRN25-12D vacuum contactor and assembled electric equipment can be used for three-poles circuit grid and urban terminal power supply distribution and industrial power equipment. Assembled equipment is more reliable, economical than circuit breaker in protection of circuit grid, bi-radial power supply unit and cabinet transformer substation. Manual operation routine is in the right hand of load break switch. We can also supply front or left operation according to customer's requirement.

Ambient condition

1 Ambient temperature: max +40°C min -25°C(conveyance under -30°C is allowed), average temperature ≤35°C within 24 hours

2 Altitude: ≤1000m

3 Relative humidity: daily average relative humidity: ≤95%; monthly average relative humidity≤90%

4 Earthquake intensity: ≤8 degree

5 Air contamination degree: II degree

6 The installation should be free from fire, explosion, severe vibration, chemical corrosion and serious pollution

7 Non-frequent violent vibration.
