Lewmar 325AMP ANL Type Fuse

The Lewmar 325AMP ANL Type Fuse is a heavy-duty electrical protection component designed for marine bow thruster systems and other high-amperage DC applications. Built to meet the demands of serious boaters and marine equipment operators, this fuse safeguards critical electrical circuits by interrupting power flow during overcurrent conditions. Whether you're running a bow thruster on a center console, cabin cruiser, or larger vessel, the 325-amp capacity makes this fuse essential for reliable, safe marine operations in any season.

The ANL (Mega) fuse design is specifically engineered to handle sustained high-current loads while maintaining fast response times during fault conditions. The 325-amp rating indicates this fuse is rated to carry up to 325 amperes under normal operation and will blow decisively if circuit amperage exceeds safe limits—protecting motors, wiring, and control systems from thermal damage or fire risk. ANL-style fuses use a low-inductance cartridge design with silver-plated copper contacts, ensuring minimal voltage drop and reliable performance across thousands of charge and discharge cycles typical in marine electrical systems.

This fuse is compatible with standard ANL fuse holders found on most modern marine electrical systems and bow thruster installations. It's the ideal replacement when upgrading existing protection or building a new thruster circuit, and should be paired with ANL fuse holders rated for 325 amps or higher. Keep a spare on board for extended trips—a blown fuse in rough water is a quick, inexpensive fix that keeps your boat maneuvering reliably when you need it most.
