Selection for W type motor current-limit fuse box

  • When started with full voltage, Rated current ≈ twice of loaded motor current;When started under other circumstances, rated current ≈ 1.25 times of loaded motor current. For directly started motor, fuses of proper rated current should be selected according to the following formula;
  • Refer to Time-current Characteristics Diagram for Selection of proper H.V. fuse link, Rated current of fuse link should be 1.3 times than loaded motor current.
