Sea-Dog 445110-1 ATO/ATC Fuse, 10 Amp, 5-Pack

The Sea-Dog 445110-1 is a 10 amp ATO/ATC style automotive blade fuse designed to protect electronic devices and circuits aboard a boat. Each set includes 5 fuses, making it easy to keep a spare on hand or replace a full bank of blown fuses in one go. The fuse body is constructed of injection molded nylon for durability in the marine environment, while the connector blades are tin plated for superior electrical conductivity and improved resistance to corrosion caused by moisture and salt air. This is a fast acting (open) style fuse, meaning it is built to interrupt current quickly once the rated 10 amp threshold is exceeded, helping prevent damage to wiring and connected equipment. The standard ATO/ATC blade footprint means it is a through-hole mount fuse that fits any standard ATO/ATC fuse block or holder commonly used in 12-volt marine electrical panels. At 3/4 inch in both blade length and body height, with a 3/16 inch blade width and 9/16 inch blade spacing, it matches the universal dimensions of standard automotive-style blade fuses, so it is simple to identify and replace. Whether topping off a fuse block, building a spare parts kit, or replacing a fuse that has blown from an overloaded circuit, the Sea-Dog 445110-1 provides a reliable, correctly rated replacement.

How many fuses come in a set? This set contains 5 individual 10 amp ATO/ATC fuses.

What style of fuse is this? It is a standard ATO/ATC (fast acting, open style) blade fuse, the same footprint used in most automotive and marine 12-volt fuse blocks.

What are the physical dimensions of the 445110-1 fuse? The fuse blade and body each measure 3/4 inch, with a blade width of 3/16 inch and blade spacing of 9/16 inch, matching standard ATO/ATC blade fuse dimensions.

What material is the Sea-Dog 445110-1 made from? The body is injection molded nylon, and the connector blades are tin plated for improved conductivity and corrosion resistance in marine environments.

Will this fuse fit my existing fuse block? Yes, the 445110-1 uses the standard ATO/ATC through-hole mount blade design, so it fits any fuse holder or panel built for standard ATO/ATC blade fuses.

Is this a fast-acting or slow-blow fuse? The 445110-1 is a fast acting (open style) fuse, designed to interrupt current quickly once the circuit exceeds 10 amps.

Why does tin plating on the blades matter? Tin plating on the 445110-1 connector blades improves electrical conductivity and helps resist corrosion from moisture and salt air, which is important for marine electrical systems.

How much does a set of these fuses weigh? A set of Sea-Dog 445110-1 fuses weighs 0.026 pounds.

Is there a version of this fuse with more than 5 pieces? The 445110-1 part number is packaged as a 5-fuse set; a separate 20-fuse set is available under a different Sea-Dog part number for the same 10 amp rating.

What is the UPC for the Sea-Dog 445110-1? The UPC for this 10 amp ATO/ATC fuse set is 035514446525.
