Blue Sea Systems 5026 ST Blade Fuse Block – 12 Circuits with Ground, 100A

Powerful, organized DC protection for marine and mobile systems

The Blue Sea Systems 5026 ST Blade Fuse Block with Negative Bus delivers clean, reliable protection for up to twelve branch circuits. With a built‑in negative bus, all ground connections terminate in one location, helping reduce wiring clutter and speeding up troubleshooting on boats, RVs, overland rigs, and custom electrical installs.

Designed for harsh environments, this fuse block uses tin‑plated copper buses and durable fuse clips that resist corrosion while maintaining strong conductivity. A clear, snap‑on insulating cover protects terminals from accidental contact and offers recessed labeling areas for quick circuit identification. An integrated spare fuse storage keeps essential fuses handy, minimizing downtime during maintenance.
