AAA Blade Fuse Holder is a practical circuit-protection and power-distribution solution for organising multiple DC electrical circuits on boats, yachts, RVs, camper vans, automotive systems, and other low-voltage installations. Designed for standard blade fuses, this marine fuse box is available in 4-gang, 6-gang, and 10-gang versions, allowing installers to select the right number of protected circuits for their electrical layout. The 10-gang version shown is model 11514-10, while the available range also includes 11514-04 and 11514-06 models.

This blade fuse holder helps centralise individual circuit protection for equipment such as navigation lights, bilge pumps, cabin lights, livewell pumps, USB charging ports, marine electronics, deck accessories, ventilation fans, and other separately fused 12V or DC-powered loads. Instead of using several individual inline fuse holders, a boat fuse box keeps fuse positions organised, easier to inspect, and more convenient to service during maintenance or troubleshooting.

Each circuit is rated for up to 30A maximum output, while the main input supports up to 100A maximum. The unit uses tin-plated brass terminals, helping provide dependable electrical contact in marine and mobile electrical installations. It accepts #4–6 AWG input wire and #12–16 AWG output wire, making it suitable for a properly planned multi-circuit wiring system. The specified maximum terminal torque is 20 in-lb (2.25 Nm), with a maximum mounting torque of 8 in-lb (0.9 Nm).

A major benefit of this marine fuse holder is its red LED fault indication. When a fuse is broken, the corresponding red LED illuminates, helping users identify the affected circuit without checking every fuse one by one. This can save time when troubleshooting electrical accessories on a boat, especially where several circuits are installed in one compact area. The clear insulating cover protects the fuse area from dust and water exposure while allowing the fuse positions and LED indicators to remain visible. The latch-open cover also allows access when fuse inspection or replacement is required.

The AAA Blade Fuse Holder uses a PBT base and a PC clear cover. The base is listed with a UL 94V-0 flame rating, while the cover is listed with a UL 94V-2 flame rating. Its compact multi-circuit layout makes it a useful choice for new electrical installations, refits, accessory upgrades, and organised replacement of older fuse arrangements. Choose the 4-gang version for smaller electrical systems, the 6-gang version for medium installations, or the 10-gang blade fuse holder for boats and vehicles requiring more individual protected circuits.
