Blue Sea 5163 750A ANL Fuse

The Blue Sea 5163 750A ANL Fuse is the marine-grade DC circuit protection solution serious boaters and anglers rely on for reliable electrical performance in demanding saltwater and freshwater environments. Whether you're running a high-powered auxiliary system, multiple battery banks, or heavy-draw electronics on extended trips, this ANL fuse delivers the robust protection your vessel's main circuits demand. Engineered to Blue Sea's exacting standards, it's the choice for boat owners who understand that electrical failures at sea create safety and navigation risks that proper protection prevents.

Built with silver-plated connector blades, the Blue Sea 5163 ANL Fuse resists corrosion from salt spray, moisture, and the harsh marine environment—a critical feature in systems where oxidized connections can cause voltage drop and circuit failure. Its 750-ampere rating suits large battery banks and high-capacity distribution systems, while the 6,000 Ampere Interrupt Capacity (AIC) exceeds American Boat and Yacht Council (ABYC) standards for main DC circuit protection. A visible blown-fuse indicator lets you confirm fuse status at a glance, eliminating ambiguity during troubleshooting and reducing downtime when you need reliable power most.

This fuse is designed for installations where amperage demands exceed standard fuse ratings—dual battery systems, inverters, thruster motors, and large-capacity charging systems on fishing vessels, cruising boats, and commercial marine platforms. Installation is straightforward in any ANL-compatible fuse holder, making retrofit or upgrade work fast and reliable. If you operate a boat with substantial electrical load, shore-based charging infrastructure, or mission-critical systems, the Blue Sea 5163 ANL Fuse provides the confidence that your circuits are protected to marine standards.
