FUSE (P/N ack-300) - New Surplus, As Removed

The ack-300 is an aircraft fuse that protects DC electrical circuits from overcurrent conditions. When excessive current flows through a circuit, the fuse element melts and opens the circuit, preventing damage to wiring and connected equipment like avionics or lighting systems. Installed in the specified fuse holder per the aircraft wiring diagram, it provides automatic fault protection without manual intervention.

Replacement fuses must match the amperage rating listed in the maintenance manual to ensure proper protection. Conforms to SAE AS5372A specifications for aircraft current-limiter fuses.
