Cole Hersee Standard 4 ATO Fuse Block w/LED Indicators

The Cole Hersee Standard 4 ATO Fuse Block with LED Indicators delivers consolidated circuit protection for marine electrical systems. This compact fuse distribution block accepts standard ATO fuses and consolidates multiple circuits into a single, organized mounting point—eliminating the need for scattered fuse holders throughout your vessel's electrical infrastructure.

The integrated LED blown fuse indicators are the key feature that sets this block apart. Rather than relying on visual inspection or testing continuity to diagnose a blown fuse, each position has a dedicated LED that illuminates when a fuse fails. This dramatically reduces troubleshooting time on the water—critical when you need to restore power to navigation, fish-finding electronics, or bilge pumps quickly. The 3 x 2 x 7 inch form factor mounts easily in engine compartments or cabin wiring bays, and the RoHS-compliant design meets environmental standards for marine manufacturing.

This fuse block is ideal for anglers upgrading their electrical systems—whether you're rigging a weekend fishing boat with multiple accessories or managing the complex power distribution on a larger offshore vessel. Weekend fishermen benefit from the quick LED diagnostics when adding fish finders, GPS units, or underwater lighting. Serious offshore anglers managing dozens of electrical circuits appreciate the space-saving, organized approach that keeps the electrical bay clean and accessible for future maintenance.

The 4-position design provides the right balance between capacity and compact installation—enough circuits for most recreational boats without excessive bulk. Cole Hersee fuse blocks are standard-issue in marine OEM applications and are widely used by boat builders and marine electricians as drop-in upgrades for older or damaged distribution systems.
