Blue Sea 5503 ANL 750 Fuse Block w/ Cover

The Blue Sea 5503 ANL 750 Fuse Block w/ Cover is a heavy-duty electrical distribution hub designed for serious vehicle modification projects, custom automotive wiring, and auxiliary power systems. Built for mechanics and enthusiasts who demand reliable circuit protection when upgrading alternators, winches, auxiliary lighting, or adding aftermarket electronics, this fuse block consolidates multiple circuits into one compact, organized component.

The 5503 ANL fuse block accommodates ANL fuses rated at 750 amps continuous capacity, making it suitable for high-amperage applications where standard blade fuses fall short. The integrated cover protects terminals from accidental contact, dust, and corrosion—critical for vehicles exposed to off-road conditions or salt environments. Its compact footprint (8 x 3 x 10 inches) fits neatly in engine bays or auxiliary power boxes without demanding excessive real estate, while it weighs just 1.05 lbs, keeping installation weight minimal.

Engine swap builders, truck bed re-wiring projects, and mobile auxiliary power systems benefit most from this fuse block's robust construction and professional-grade reliability. Whether you're running an upgraded alternator circuit, powering a hydraulic winch, distributing current to LED light bars, or managing multiple auxiliary loads in a custom installation, the Blue Sea 5503 ANL 750 provides reliable current handling.
