Product Details

1. FN12 type indoor 10kv 11kv 12kv 630A Air load break switch

 

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.

 

2. Service Condition

 

 1. The ambient air temperature: MAX.: +40°C, Min.: -10°C.
 2. The altitude does not exceed 1000m.
 3. The relatire humidity of air daily average ≤90%, monthly average ≤ 95%.
 4. The ambient air should not be obviously polluted by corrosivity or the flammability gas and steam. etc.
 5. The working situation without frequent violent.
