Item:FN12

FN12 indoor air pressure LBS vcb electrical
  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.

  • Service Condition:
    A. The ambient air temperature:  Max.: +40 °C. Min: -10 °C.
    B. The altitude ≤ 1000m.
    C. The relatire humidity of air. daily average ≤ 90%. monthly average ≤ 95%.
    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 Ⅱ.
