Product Description

Product Description

FZRN25 type vacuum load switch

FZRN25 type vacuum load switch and combined electrical appliances, suitable for three-phase AC 50Hz ring network or
terminal power supply and industrial power equipment, for load control and short circuit protection, load switches divide and
close the load, closed-loop current, no-load transformer and cable charging current. The combination appliances can open and close
any current up to the rated short-circuit current. It adopts direct-acting isolating break and vacuum arc chamber linkage. With
manual and electric function

Work conditions
The normal conditions of use load switch and switchgear is suitable for the following.if the actual use of the environment
condition is diferent from the normal conditions of use.
The ambient temperature: 40 ºC lower limit:-25 ºC;
Altitude: not more than 1000M:
Relative humidity: daily average value is greater than 95%, on average less than 90%.
Saturated vapor pressure: daily average value not more than 2.2×10-3Mpa,monthly average value not more than 1.8×10-3Mpa;
Installation location: no fire, explosion, pollution,chemical corrosion and frequent violent vibration of the place;
Earthquake intensity: no more than 8.
Pollution grade: II

6.It should be Installed in the places without fire, explosion, serious pollution, chemical erosion and violent vibration.
