FUSE (P/N mdl-4) - New Surplus

The mdl-4 is a 3AG glass cartridge fuse (1/4 in × 1-1/4 in) with time-delay characteristics and ferrule ends. Designed to UL 248-14 standards, this fuse protects avionics and electronic circuits from overcurrent conditions. The ferrule construction mounts directly into standard 3AG fuse holders or clips found in aircraft electrical panels.

Select the ampere rating according to your equipment manual and install in a compatible 3AG holder. Time-delay design prevents nuisance trips during normal circuit inrush conditions while providing protection against sustained overcurrent faults.
