Blue Sea Systems Terminal Fuse - ABYC-Compliant DC Main Circuit Protection, 50A to 100A
Blue Sea Systems Terminal Fuse - ABYC-Compliant DC Main Circuit Protection, 50A to 100A
Blue Sea Systems Terminal Fuses provide reliable, ABYC-compliant DC main circuit protection for marine electrical systems. Designed to mount in a compatible Terminal Fuse Block (such as PN 5191 or PN 2151), these fuses protect battery banks, bus bars, and heavy-gauge feeder cables from overcurrent damage without the bulk of a traditional circuit breaker. Each fuse is color-coded by amperage for quick visual identification and features a clear inspection window so you can confirm fuse condition at a glance, without pulling it from the block. Built for continuous marine duty, they carry a 10,000 AIC interrupt rating at 14 Volts DC and are ignition protected, making them safe for use aboard gasoline-powered boats near the engine compartment.

Sizes & Options
This line is available in two amperage ratings, each color-coded to match Blue Sea Systems' standard convention: 50 Amp (Red, PN 5177) and 100 Amp (Yellow, PN 5183). Select the amperage that matches the circuit you are protecting, sized to your wire gauge and the connected load or battery bank per ABYC guidelines. Both fuses require a separately purchased Terminal Fuse Block, such as PN 5191 or PN 2151, and should never be mounted directly to a battery terminal.
