The Blue Sea 5056 ST-Blade Water Resistant Fuse Block with Cover is an essential component for professional-grade electrical distribution in modern vehicles and custom builds. Ideal for those upgrading a truck's auxiliary power system, installing winch controls, or wiring auxiliary lighting and accessory circuits, this fuse block serves as the central hub for your installation needs.

Constructed with marine-grade materials, this unit is designed to withstand harsh environments where vibration, moisture, and salt spray can compromise lesser components. It features ST-blade terminal technology, allowing for the use of standard automotive fuses and providing secure, corrosion-resistant connections that remain intact under thermal cycling or engine vibration. The integrated water-resistant cover protects terminals and fuse positions from spray, dust, and incidental moisture, making it suitable for mounting in challenging locations.

This fuse block is perfect for technicians and enthusiasts who require reliability in high-amperage circuits where failures are not an option. Its compact design allows for flexible mounting in tight spaces without sacrificing terminal count or current capacity. Weighing only 0.5 lbs, it adds minimal weight to your electrical system while providing the necessary amperage distribution for multiple accessories.
