Description
Product Overview
The Blue Sea Systems 5005 ANL fuse block is engineered to provide dependable over‑current protection for a wide range of marine and off‑grid electrical applications. Constructed from high‑impact plastic, the housing resists corrosion and mechanical stress while the insulated cover complies with ABYC and USCG requirements, ensuring safety in harsh environments. The block features a swing‑out design that allows technicians to replace a blown fuse without the need to remove mounting fasteners, dramatically reducing service time and downtime. With a current rating of up to 300 A and a voltage rating of 32 V DC, this fuse block can handle substantial loads typical of trolling motor circuits, battery banks, and auxiliary equipment. The product dimensions of 4.5 inches wide by 1.65 inches high and a centerline length of 8 inches make it a compact yet powerful solution for panel‑mount installations. UL 94‑V0 rated material provides excellent heat resistance, and the stainless‑steel studs offer superior torque resistance for a secure electrical connection.
Usage
Designed for both professional installers and DIY enthusiasts, this fuse block excels in a variety of settings. On recreational vessels, it safeguards critical systems such as navigation lights, communication equipment, and high‑draw devices like winches and pumps. In remote off‑grid cabins, the block protects solar charge controllers, inverter circuits, and battery management systems from overloads. The ability to accept 5/16″ (M8) ring terminals provides flexibility for wiring configurations, allowing users to route cables in any direction through the cover breakouts. The insulated cover not only meets safety standards but also protects the fuse contacts from accidental short circuits during maintenance. Whether mounted on a dedicated electrical panel or integrated into a custom enclosure, the 5005 model delivers reliable performance in environments where reliability and ease of service are paramount.
