Keep your 12V or 24V DC electrical system organized, protected, and easy to service with the Blue Sea Systems ST Blade Fuse Block – 12 Circuits with Negative Bus and Cover (Part #5026). Designed for marine, RV, overland, van life, emergency response, and commercial vehicle applications, this premium fuse block provides a clean, centralized solution for distributing power to multiple DC accessories while reducing wiring complexity.

Featuring 12 independently fused circuits, an integrated negative bus, and a protective insulating cover, the ST Blade Fuse Block is ideal for powering lights, radios, GPS units, routers, inverters, refrigeration, water pumps, fans, and other 12V or 24V electronics. Instead of multiple inline fuses scattered throughout your electrical system, this fuse block consolidates circuit protection into one easy-to-access location, making troubleshooting and future upgrades significantly easier.

The integrated negative bus bar simplifies wiring by providing a dedicated return path for each circuit, resulting in cleaner installations and fewer external bus bars. Built with tin-plated copper buses and fuse clips, the fuse block offers outstanding corrosion resistance and long-term electrical reliability in harsh marine and mobile environments.

Its protective cover meets ABYC and USCG insulation requirements while featuring a convenient push-button latch for quick fuse access. The cover also stores two spare blade fuses and includes write-on circuit labels, helping installers quickly identify each connected circuit during maintenance or troubleshooting.

Supporting standard ATO® and ATC® blade fuses (sold separately), the Blue Sea Systems 5026 is rated for 100 amps total with up to 30 amps per individual circuit and supports DC systems up to 32V. Whether you're building a new electrical system or upgrading an existing fuse panel, this professional-grade fuse block delivers the organization, safety, and durability trusted by installers worldwide.
