Blue Sea 5175 30A Fuse Terminal

The Blue Sea 5175 30A Fuse Terminal is a compact DC circuit protection device engineered for marine electrical systems, particularly suited to installations on battery banks and main power circuits. This light green terminal fuse meets ABYC (American Boat and Yacht Council) standards for DC main circuit protection on large battery installations, making it the preferred choice for serious boaters who demand reliable, code-compliant power management.

Rated for 30-amp service, this fuse terminal features an interrupt rating that satisfies ABYC requirements for DC systems and is ignition-protected, allowing safe installation aboard gasoline-powered vessels. The clear window design provides visual confirmation of fuse condition—a blown fuse is immediately apparent without disconnecting terminals or removing the unit. The compact form factor (3 x 1 x 5 inches) fits tight engine compartments and electrical lockers common on fishing boats and cruising yachts. Must be paired with a Blue Sea terminal fuse block for proper installation.

This product serves weekend anglers and offshore fishing crews running dual battery systems, trolling motors, or upgraded electrical loads. Cruising sailboat owners, trawler captains, and anyone expanding onboard power systems will benefit from its standards-compliant design and fail-safe architecture. The 30-amp capacity bridges auxiliary circuits and smaller main bus installations where heavier 50 or 100-amp fuses would be excessive.

Terminal fuse blocks have become the marine industry standard for modular DC protection because they isolate battery circuits at the source, prevent nuisance trips, and simplify troubleshooting. The Blue Sea 5175 fits seamlessly into systems already using Blue Sea components, ensuring compatibility and consistent protection across your vessel's electrical architecture.
