Blue Sea Systems ATO/ATC Fuse Block 6 Circuit with Ground – BSS-5025
The BSS-5025 is a 6-circuit ATO/ATC blade fuse block with an integrated ground bus, designed for organizing and protecting multiple DC accessory circuits in marine electrical systems. Each circuit is individually fused, and the built-in negative bus simplifies wiring by providing a central ground termination point — reducing clutter and keeping installations clean and serviceable.

- 12V and 24V DC panel builds in boats, RVs, and off-grid systems
- Powering navigation lights, bilge pumps, electronics, and cabin accessories
- Custom electrical panels where a combined positive fuse block and negative bus is needed
- Replacement or upgrade for existing ATO/ATC fuse block installations

- 6 individually fused circuits using standard ATO/ATC blade fuses
- Integrated ground bus — simplifies negative wiring and reduces terminal clutter

Parts Desk Insights
Best suited for builders wiring up to 6 accessory circuits who want a single block that handles both positive fusing and negative termination in one unit. The integrated ground bus is the key advantage here — it eliminates the need for a separate negative bus bar and keeps the installation compact. If you need more circuits, the BSS-5026 12-circuit version is the natural step up. For a cleaner install with a protective cover included, consider the ST Blade 5025 with Cover. Fuses are not included — pair with ATO/ATC blade fuses in the appropriate amperage for each circuit.
