Blue Sea ATO/ATC Fuse Pack - 5 Amp - 25-Pack

The Blue Sea ATO/ATC Fuse Pack – 5 Amp – 25-Pack delivers reliable circuit protection for marine electrical systems where dependability matters most. After years running boats and managing complex 12-volt installations, you learn that quality fuses aren't an afterthought—they're your first line of defense against electrical fires and system damage. This 25-pack ensures you're never caught on the water without backup protection, making it an essential component for any serious boater's spare parts inventory.

Each 5-amp fuse in this pack is designed to work with Blue Sea Systems' ATO/ATC fuse holders, the industry standard for modern marine electrical panels. ATO/ATC fuses feature a ceramic body with silver-plated copper contacts that resist corrosion—critical when saltwater spray and humidity are constant threats. The 5-amp rating protects moderate-draw circuits such as lighting, bilge pumps, and navigation electronics without nuisance blows, while the compact form factor fits standard marine fuse blocks with zero modification needed.

Experienced anglers, cruisers, and commercial operators trust Blue Sea Systems because the company understands saltwater environments. This 25-pack quantity covers multiple circuits or gives you redundancy across fishing season without inventory gaps. Installation is instantaneous—simply locate your ATO/ATC fuse holder, turn off the circuit breaker, remove the blown fuse, and insert a replacement.
