Blue Sea 5258 MIDI/AMI Fuse 150 Amp - Pair

The Blue Sea 5258 MIDI/AMI Fuse 150 Amp – Pair is a marine electrical safety essential for any serious boater or angler running moderate to high-amperage systems. Whether you're powering dual GPS chartplotters, a large trolling motor, cabin lighting, and refrigeration, or running a robust bilge pump and automated systems, these fuses protect your vessel's electrical infrastructure from catastrophic failure. Engineered to Blue Sea's exacting marine standards, this pair offers redundancy and reliability for boats relying on 150-amp circuit protection.

Each MIDI/AMI format fuse features tin-plated copper contacts that resist corrosion from salt spray, humidity, and constant vibration—critical in saltwater and brackish environments where oxidation compromises electrical connections. The clear polycarbonate cover allows instant visual confirmation of fuse integrity; a blown fuse is immediately obvious, eliminating guesswork during troubleshooting on the water. Color-coded design enables fast amperage identification in low-light cabin conditions, and the compact 2 x 1 x 3-inch form factor fits standard marine fuse blocks without requiring panel modifications or custom wiring harnesses.

Anglers and cruisers maintaining systems drawing 120+ amps—such as larger center-console boats with integrated electronics, live wells, and heating—benefit most from carrying a spare pair on board. Installation is straightforward: simply insert into compatible MIDI/AMI fuse holders in your distribution panel. Keep extras in your emergency kit; a blown 150-amp fuse at sunset far from port can leave you without navigation, communication, or propulsion. Verify your vessel's fuse block specifications match MIDI/AMI standards before ordering.
