Sea-Dog ATC/ATO Automotive Fuse, 5 Amp, Pack of 5 (445105-1)

The Sea-Dog 445105-1 is a standard ATC/ATO blade-style automotive fuse rated at 5 amps, sold in a pack of 5. Built with a tin-plated copper element inside an injection-molded nylon housing, it is designed to protect low-draw circuits on boats and other 12-volt electrical systems from overcurrent damage. The through-hole mount blade terminals are sized to the universal ATC/ATO standard, so this fuse drops into any fuse block, panel, or holder built for that footprint, making it a convenient replacement or spare for marine wiring, accessory circuits, gauges, and other light-duty loads.

Each fuse is individually rated and color-coded per the ATC/ATO amperage standard so the correct value is easy to identify at a glance during troubleshooting or replacement. Keeping a pack of these on hand is a practical way to avoid being stranded by a blown fuse, since the compact size and low cost make them easy to store as spares aboard the boat, in a tackle box, or in a glove compartment.

Frequently Asked Questions

What amperage is the Sea-Dog 445105-1 fuse rated for? The Sea-Dog 445105-1 is rated for 5 amps, which suits low-draw circuits such as gauges, small accessories, and indicator lights.

How many fuses come in a pack? This listing for part number 445105-1 includes 5 fuses per pack.

What style of fuse is this? It is a standard ATC/ATO blade-style fuse, the common automotive and marine blade fuse footprint used in most 12-volt fuse blocks and panels.

What material is the Sea-Dog 445105-1 fuse made of? It uses a tin-plated copper fuse element housed in an injection-molded nylon body.

Will this fuse fit any standard ATC/ATO fuse holder? Yes, the 445105-1 uses the universal ATC/ATO blade and through-hole mount dimensions, so it fits any fuse block, panel, or holder built for that standard.

Is this fuse suitable for marine use? Yes, Sea-Dog markets the 445105-1 as part of its boat fuse line, and the tin-plated copper element resists corrosion better than bare copper in a marine electrical environment.

How do I know if a 5 amp fuse has blown? ATC/ATO fuses like the 445105-1 have a visible metal strip inside the housing; a break or scorch mark in that strip indicates the fuse has blown and needs replacing.

Can I mix this with other amperage fuses in the same panel? The 445105-1 is rated specifically at 5 amps; each circuit should use the fuse amperage specified for that circuit, so do not substitute a different rating without checking the circuit's requirements.

Is this a genuine Sea-Dog part? Yes, part number 445105-1 is a genuine Sea-Dog Line fuse, not a generic substitute.
