FUSE (P/N mdl-3) - New Surplus

The MDL-3 is a 3-ampere, 250-volt time-delay glass cartridge fuse for aircraft electrical circuit protection. This 3AG-format fuse provides overcurrent protection in low-voltage DC avionics sub-circuits and electrical equipment, allowing brief inrush currents while interrupting sustained overloads. The glass cartridge design with metal end caps enables visual inspection of the internal element.

Replace only with an identical MDL-3 rating and type per aircraft maintenance manual specifications and FAA AC 43.13-1B guidance. Proper fuse selection ensures system safety and prevents damage to sensitive avionics and control circuits.

Is the mdl-3 compatible with my aircraft's avionics suite?

Avionics compatibility depends on your aircraft model and existing installation. The FUSE is available in: New Surplus. We recommend checking your aircraft's wiring diagrams and STC documentation, or contact our avionics team for compatibility assistance.

Does the mdl-3 come with an 8130-3 airworthiness tag?

Availability of an FAA 8130-3 tag depends on the part condition. Overhauled and repaired units typically include 8130-3 documentation. As-removed units may include a removal tag with trace history. Contact us for specific documentation on the condition you need.

Do you offer bench testing for the mdl-3?

We can arrange bench testing through our network of FAA-certified repair stations. Call (904) 998-9101 for testing availability and turnaround times, or submit an RFQ with your specific requirements.
