12.0 Input Fuse Types and Ratings
Inverter input fuses are provided to disconnect the inverter from input power in the event of a component 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 on the next page shows the N3 input fuse ratings.
To protect the inverter most effectively, use fuse types RK5 or CC/T with a current-limit function.
