Fuse Types and Ratings
Inverter input fuses are provided for safely disconnecting the inverter from the input power in the
event of
a failure in the inverter‘s power circuitry. The inverter‘s electronic protection circuitry is
designed to clear inverter output short circuits and ground faults without blowing the inverter input
fuses. The table below shows the EV input fuse ratings; To protect the inverter most effectively,
use fuses with current-limiting capabilities.
