FN12-12(D) Indoor High Voltage 12kV Load Break Switch

Application

 

It is a three phase H.V. switch equipment of 12KV, 50Hz for breaking or closing load current., no-load transformer cable charging current and closing short-circuit current. The load switch with earth switch can bear short-circuit current. It is made up of FN12-12D load switch and S()LAJ-12(XRNT()-10) H.V. current-limiting fuse box. It can break any current, load switch breaking working current and fuse box breaking short-circuit current, jointly breaking any current between short-circuit current. Meantime, fuse box make the switch off of with the striker.

 

Standard

 

a. GB3804-90 <<3-63KV AC H.V load switch>>.

b. GB16926-1997 <>(eqv, IEC62271-2002).

c. GB1995-89 <>.

 

 

Environmental conditions for operation

 

A. The ambient air temperature: Max.: +40 °C. Min: -10 °C.

B. The altitude ≤ 1000m.

C. The relative humidity of air. daily average ≤ 90%. monthly average ≤ 95%.

D. The ambient air should not be obviously polluted by corrosively or the flammability gas and gleam. etc.

E. Without frequent shake.

F. Environment degree: grade .

 

If requirements are not mentioned above, users can fix them with the manufacturer.
