Sea-Dog ATO/ATC Fuse 445107-1, 7.5 Amp, Pack of 5

The Sea-Dog 445107-1 is a 7.5 amp ATO/ATC style automotive blade fuse built for marine electrical systems where corrosion resistance matters. Each fuse is constructed of injection molded nylon housing with tin plated connector blades, giving it superior conductivity and improved resistance to corrosion in a salt water environment compared to standard uncoated blade fuses. The fast acting (open) design provides reliable overcurrent protection for onboard electronic devices and circuits, cutting power quickly if amperage exceeds the rated 7.5 amps to help prevent damage to connected equipment.

This is the standard ATO/ATC blade profile, measuring 3/4 inch by 3/4 inch overall with 3/16 inch and 9/16 inch blade dimensions, so it drops into the same fuse holders and blocks used throughout automotive and marine 12-volt wiring. It mounts via through-hole style blade contacts. Fuses are sold in a card of 5, making it easy to keep spares on hand for panels, bilge pumps, lighting circuits, and other 7.5 amp rated accessories. Always confirm the amperage and physical size required by your specific circuit before installing.

Frequently Asked Questions

What amperage is the Sea-Dog 445107-1 fuse rated for? The Sea-Dog 445107-1 is rated for 7.5 amps, so it should only be used on circuits designed for that amperage.

Is this an ATO or ATC fuse? It is both -- the 445107-1 uses the standard ATO/ATC blade fuse profile, which is a common automotive and marine fuse standard, so it fits any holder built for that style.

How many fuses come in a pack? Sea-Dog part 445107-1 is sold as a card of 5 fuses.

What are the physical dimensions of this fuse? The 445107-1 measures 3/4 inch by 3/4 inch overall, with a 3/16 inch and a 9/16 inch blade dimension, matching the standard ATO/ATC blade fuse footprint.

What is the fuse body made of? The housing is injection molded nylon, and the connector blades are tin plated for improved conductivity and corrosion resistance.

Will this fuse hold up in a marine environment? Yes -- the tin plated blades on the Sea-Dog 445107-1 are specifically designed to resist corrosion in a salt water environment better than uncoated automotive fuses.

How does this fuse mount into a fuse block? The 445107-1 uses a through-hole mount, with its blade contacts pushing directly into a standard ATO/ATC fuse holder or block.

Is this a fast-acting or slow-blow fuse? The Sea-Dog 445107-1 is a fast acting (open) style fuse, meaning it cuts power quickly once current exceeds its 7.5 amp rating.

What is the weight of this fuse pack? The Sea-Dog 445107-1 fuse card weighs 0.026 pounds.

Can I use this fuse in a car instead of a boat? Yes -- the ATO/ATC blade style used by the 445107-1 is a shared automotive and marine standard, so it works in either application as long as the amperage and physical size match the circuit.

What is the UPC for this product? The Sea-Dog 445107-1 7.5 amp fuse carries UPC 035514446488.
