FN-12 Series Indoor High Voltage Load Break Switch (With Fuse And Without Fuse)

Product Overviews

FN-12DR is used in three-phase AC power network of AC 50Hz, rated voltage 12KV for breaking load current and controlling short-circuit current.
FN(C)-12 type H.V. load switch and fuse box is based on the FN7-12 series H.V. load switch with operating mechanism, make the installation more simpler, can meet orders needs.

Working Conditions

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.
