Blue Sea ATO/ATC Fuse Pack - 2 Amp - 25-Pack

The Blue Sea ATO/ATC Fuse Pack - 2 Amp - 25-Pack delivers reliable circuit protection for marine electrical systems where dependability is non-negotiable. Whether you're running navigation equipment, fish finders, or cabin lighting, these fast-acting fuses safeguard your boat's critical electronics from voltage spikes and short circuits. Built to the same standards as automotive fuses but engineered for the corrosive saltwater environment, this 25-pack ensures you'll have spares on hand when you need them most—far from the nearest chandlery.

ATO/ATC fuses are the industry standard for marine and automotive applications, recognized by their dual-blade design that slides into common panel-mount holders. The 2 amp rating suits low-draw circuits—instrument panels, LED nav lights, and control modules—where faster response prevents component damage during faults. Tin-plated connector blades resist oxidation and corrosion, critical in saltwater and high-humidity conditions where standard brass corrodes quickly and increases resistance over time. Fast-acting construction means these fuses clear faults in milliseconds, protecting sensitive solid-state electronics that cannot tolerate sustained overcurrent.

Serious boaters, commercial fishermen, and liveaboard cruisers rely on proper fuse redundancy to minimize downtime and electrical troubleshooting at sea. A 25-pack covers multiple circuits across your vessel, allowing strategic placement in engine compartments, cabin panels, and backup systems without rationing spares. Compatible with any standard ATO/ATC fuse block or panel holder found on modern boats, this pack meets marine electrical codes and integrates seamlessly into existing systems—whether you're retrofitting an older vessel or maintaining a new build.
