Blue Sea 5105 MEGA®/AMG® Fuse - 200AMP

The Blue Sea 5105 MEGA®/AMG® Fuse – 200AMP is the economical standard for circuit protection in the 100–300 ampere range, engineered specifically for use with Blue Sea Systems' MEGA®/AMG® fuse block platforms. Built to protect critical marine electrical systems on everything from center consoles to serious offshore vessels, this fuse delivers reliable performance where saltwater corrosion and voltage spikes demand dependable protection.

Rated for 200-amp continuous protection, the 5105 MEGA®/AMG® fuse is designed to interrupt overcurrent conditions before they damage wiring harnesses, battery banks, or integrated electrical loads common in modern marine systems. The fuse's compact form factor—measuring just 5 inches in length with a weight of 0.1 pounds—fits seamlessly into standard Blue Sea Systems fuse blocks without requiring extensive rewiring. Its construction and amperage rating are validated against the demands of high-amperage DC systems typical of fishing vessels, pleasure cruisers, and commercial marine applications where electrical reliability directly impacts safety and operational continuity.

Weekend anglers running dual battery banks and electronics, as well as offshore captains managing complex power distribution systems, choose MEGA®/AMG® fuses for their proven performance in marine environments. Weekend fishermen upgrading fish-finder or autopilot systems benefit from the cost-effective protection this fuse provides; serious operators managing multiple engines, inverters, and battery isolators rely on its consistent performance to keep systems online when it matters most. The 5105 fuse is an industry-standard component in Blue Sea Systems panel configurations and remains essential for anyone maintaining or upgrading a marine electrical installation.
