Blue Sea Systems 5141 60 Amp MAXI Fuse, ST-Blade Water-Resistant Blade-Style Fuse

The Blue Sea Systems 5141 is a 60 amp MAXI blade-style fuse built for marine 12-volt and 24-volt DC circuits that need a larger-capacity in-line fuse than a standard ATO/ATC blade fuse can provide. It uses the ST-Blade MAXI form factor, sized for high-current circuits such as bilge pump feeds, battery switch runs, windlass supply lines, and other heavy-draw accessory circuits on a boat's electrical panel. The fuse body is molded plastic with tin-plated connector blades that resist the corrosion marine environments cause on bare metal contacts, helping maintain a solid, low-resistance connection over time. A visible blown-fuse indicator lets you identify a tripped fuse at a glance without pulling it and testing it with a meter, which speeds up troubleshooting during a fault.

The Blue Sea Systems 5141 carries a 60 amp current rating at 32 volts and is sold as a single fuse per package. It is part of the Blue Sea Systems MAXI fuse family, which also includes the 5140 (50A), 5142 (70A), and 5143 (80A), so you can match the fuse rating to the specific circuit you are protecting. It is designed for use in a MAXI in-line fuse holder or an ST-Blade water-resistant fuse block sized for the MAXI blade footprint.

Frequently Asked Questions

What amperage is the Blue Sea Systems 5141 fuse rated for? The Blue Sea Systems 5141 is rated at 60 amps, 32 volts.

What style of fuse is the 5141? It is a MAXI blade-style (ST-Blade) fuse, a larger-capacity blade fuse designed for high-current DC circuits such as bilge pumps, windlasses, and battery switch feeds.

Does the 5141 fit a standard ATO/ATC automotive fuse holder? No, the MAXI blade footprint used by the Blue Sea Systems 5141 is larger than a standard ATO/ATC fuse and requires a MAXI-sized in-line fuse holder or ST-Blade fuse block.

What are the dimensions of the 5141 fuse? The Blue Sea Systems 5141 measures 5 x 3 x 1 inches as packaged.

How much does the 5141 fuse weigh? The Blue Sea Systems 5141 weighs 0.04 pounds.

What material is the 5141 fuse body made from? The fuse body is molded plastic, colored beige, with tin-plated connector blades.

Why are the connector blades tin-plated? Tin plating on the 5141's connector blades resists corrosion, which helps maintain a solid electrical connection in a marine environment.

How can I tell if the 5141 fuse has blown? The Blue Sea Systems 5141 has a visible blown-fuse indicator, so you can see at a glance whether it has tripped without removing it to test with a meter.

How many fuses come in a package? The Blue Sea Systems 5141 is sold as one fuse per retail package.

What other amperage ratings are available in this MAXI fuse series? The same MAXI fuse family includes the 50 amp (5140), 60 amp (5141), 70 amp (5142), and 80 amp (5143) versions, so you can match the rating to your circuit.

What voltage is the 5141 fuse rated for? It carries a 32 volt rating, suitable for standard 12-volt and 24-volt marine DC systems.

What kind of circuits is the 60 amp 5141 used for? This higher-capacity MAXI fuse is intended for heavier-draw DC circuits, such as bilge pump feeds, windlass supply lines, and battery switch runs, where a standard blade fuse's amperage would not be sufficient.
