1.1 Fuse types
Drive input fuses are provided to disconnect the drive from power in the event that a component fails in the drive’s
power circuitry. The drive’s electronic protection circuitry is designed to clear drive output short circuits and ground
faults without blowing the drive input fuses. Below table shows the EV input fuse ratings.
To protect the inverter most effectively, use fuses with current-limit function.
