Blue Sea 5068 MAXI In-Line Fuse Holder

The Blue Sea 5068 MAXI In-Line Fuse Holder is a robust electrical protection device designed for marine, automotive, and portable power applications where reliable circuit protection is non-negotiable. Built by Blue Sea Systems—a leader in electrical safety components—this inline fuse holder protects sensitive equipment and wiring from overcurrent conditions, short circuits, and electrical fires. It serves technicians, boat builders, vehicle installers, and power system designers who demand compact, dependable protection near the power source.

This MAXI-rated holder arrives pre-configured with 5 inches of #6 red lead wire, enabling quick integration into battery banks or distribution panels without additional splicing labor. The design includes two adhesive-lined sealing shrink wrap tubes that create weatherproof, corrosion-resistant connections—critical in marine and outdoor environments where moisture causes relay failure and oxidation. A firewall-mounted surface hole allows installers to stack two or more holders in tight spaces, maximizing panel density while maintaining electrical isolation between circuits. The protective shroud shields contacts from accidental bridging and debris contamination, extending service life in demanding conditions.

Marine electricians, RV system builders, and automotive customizers rely on this holder to protect auxiliary lighting, bilge pumps, winches, and auxiliary battery circuits. Its compact profile and pre-assembled lead wire reduce installation time on confined engine bays and cabin bulkheads. Weighing just 0.35 lbs, the Blue Sea 5068 MAXI In-Line Fuse Holder integrates seamlessly into existing harnesses without adding bulk or weight penalties. Verify fuse amperage rating compatibility with your circuit's maximum current draw to ensure optimal protection for your specific application.
