Blue Sea Systems 70A MAXI In-Line Fuse

The Blue Sea Systems 70 Amp MAXI Fuse (Part No. 5142) is an in-line blade-style fuse sized for MAXI fuse holders and blocks, built to protect boat wiring circuits rated for 70 amps. It uses a ST-Blade style body with tin-plated connector blades that resist corrosion in the damp, salt-air conditions typical of marine electrical systems, helping maintain a reliable connection over time. The fuse includes a visible blown-fuse indicator, so you can identify a tripped fuse at a glance without pulling it or testing it with a meter, which speeds up troubleshooting when a circuit goes dead. Choosing the correct MAXI-size wire and fuse combination for the amperage of the circuit is important for proper circuit protection, and this 70 amp rating is intended for circuits sized to that amperage. The fuse has a plastic housing in a beige color and measures 5 x 3 x 1 inches, and it is sold individually, one fuse per package. It is a through-hole mount blade design meant for use in a compatible MAXI in-line fuse holder or ST-Blade water-resistant fuse block rather than as a standalone device. This fuse is well suited for boat owners replacing a blown 70 amp MAXI fuse or building out a new circuit that calls for 70 amp overcurrent protection.
