The 422-078 is an aircraft fuse that protects electrical circuits from overcurrent damage. When current exceeds the fuse's rated amperage, the internal element opens to interrupt power flow, safeguarding wiring and connected equipment. Installed in approved fuseeholders on DC buses and avionics branches throughout the aircraft electrical system.
Before installation, verify the amperage rating and fuse type against the aircraft's Illustrated Parts Catalog and maintenance manual to ensure proper circuit protection.
