1.easy installation 2.different types available 3.Advanced design and steady performance.
DESCRIPTION
As we introduced the high technology from overseas and combined the demands from internal regions,we research and develop the new products in this electrical industry.
FN7-12DR is used in three-phase AC power network of AC 50Hz, rated voltage 12KV for breaking load current and controlling short-circuit current.
FN7(C)-12 type H.V. load switch and fuse box is based on the FN7-12 series H.V. load switch with operating mechanism, it will be easy intalled,,and meet the users' demands,
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.
