Blue Sea Systems 5005 ANL Fuse Block with Insulating Cover - 32V DC, 5/16-inch Ring Terminals

Overview

The Blue Sea Systems 5005 ANL Fuse Block with Insulating Cover is designed for flexible DC protection in compact spaces. It accepts a wide range of ANL fuse amperages, letting you tailor protection to different loads without changing the whole block. Built for reliability in demanding environments, this component supports marine, RV, and off-grid applications that rely on clean power distribution and thoughtful design.

Engineered for systems up to 32 volts DC, it accommodates 5/16-inch ring terminals to simplify wiring in tight panels, engine rooms, or utility compartments. The combination of robust materials and practical geometry helps you organize cables neatly while maintaining solid electrical contact.

Why it matters in real-world setups

In daily use, the fuse block acts as a configurable protection node within your power distribution. The ability to choose fuse amperages within a common frame means you can adapt to changing equipment or loads without replacing the entire assembly. The accessible, swing-out fuse area supports faster maintenance during inspections or upgrades, reducing downtime and easing routine servicing.

Durability matters when you’re on the move. Stainless steel studs resist corrosion and maintain a dependable connection even when hardware is torqued to specification during installation. A UL 94-V0 base provides added heat resistance, contributing to safer operation in high-heat environments such as engine bays or compact electrical lockers.

Construction, compliance, and flexibility

The insert-molded studs ensure secure fuse mounting, while the insulating cover satisfies ABYC and USCG requirements for electrical safety on boats and other vessels. The cover features breakouts that allow wire access in any direction, giving you flexible routing options for cable management in cramped installations.

What you’ll typically use it for

This fuse block pairs well with marine panels, RV power systems, and off-grid setups where space and protection options matter. Its adaptable design helps you create a neat, scalable power distribution center while keeping key safety and maintenance benefits in clear view.
