Blue Sea Systems 5125 ANL Fuse, 100 Amp, Ignition Protected, Beige

The Blue Sea Systems 5125 is a 100 Amp ANL fuse designed for main DC circuit protection on boats with large battery banks. It is ignition protected, conforming to SAE J1171, making it safe for installation aboard gasoline-powered boats within the 35-500 Amp range. The fuse carries a 6,000 Ampere Interrupt Capacity (AIC) at 32 Volts DC, satisfying ABYC requirements for main DC circuit protection. Its connector blades are silver-plated for corrosion resistance in the marine environment, and the fuse body provides visible indication of a blown condition so a blown fuse can be identified at a glance without testing. The 5125 mounts via through-hole connection and is finished in beige. It is rated for a maximum of 32 Volts DC and is sold as a single fuse. Boaters use ANL fuses like the 5125 to protect high-current wiring runs such as those between a battery bank and a main bus, inverter, or windlass, where a standard blade fuse would not be adequately rated. Pairing the fuse with correctly sized wire, and mounting it in a compatible ANL fuse block, ensures the circuit is protected at the correct amperage.
