Main technical parameters:
FN12-12 and FN12-12R is of three phases indoor use AC high voltage load switch for breaking and making the circuit of 50Hz, 12KV system under rated loading, closed loop current, no-loading transformer, cable charged current and short circuit current. The load switch equipped with earth switch can withstand short circuit current, and m-ainly used in power distribution substation and industrial electrical equipment where three phase closed loop circuit or bottom power supply system for control and protection.

Standard
a,GB3804-903~65KV AC H.V Load switch
b,GBXXX-XXAC H.V load switch with fuse box(the same IEC420-1990)
c,GB1995-89AC H.V isolate switch and earth switch

Normal Serviec Condition
A,The ambient air temperatrue : Max:+40. Min:-25.
B,The altitude ≤1000m.
C,The relatire humidity of air Daily average ≤95% . Monthly average ≤90% 
D,The ambient air should not be obviously polluted by corrosivity or the flammability gas and geam.Etc. 
E,Without frequent shake. 
F,Enviroment degree : grade .
