E. Fuse types
Drive input fuses are necessary to disconnect the drive from the power supply in the event of component failure in
the drive’s power input circuit. The iDrive’s electronic protection circuitry is designed to clear output short circuits
and ground faults without blowing the input fuses. The table below shows the iDrive EDX input fuse ratings.
To protect the inverter most effectively, use fuses with current-limit function.
It is the responsibility of the user/installer to ensure that the correct fuse protection (or other) is applied.

UL class fuses have different overload characteristics.
RK5 - type has a time delay characteristic
T-type is quick-blow
CC – type have both types of characteristic
*
Fuse ratings are based upon 250V fuses for 120V inverters, and 300V fuses for 240V inverters, and 600V
for 480V inverters.
