Compact, terminal-mounted circuit protection where space is tight.
The Blue Sea Systems BS-5023B ST Blade Fuse Block is a 4-circuit fuse block designed to mount directly to a battery terminal, providing clean, reliable protection for multiple DC accessories without additional bus bars or inline fuses.
Built using tin-plated copper buses and fuse clips, the BS-5023B is suited to harsh automotive and marine environments and is ideal for accessory feeds such as lighting, radios, compressors, control modules and auxiliary circuits.
Why it works so well in 12V systems
• Battery terminal mounting keeps wiring short and voltage drop low
• 4 fused branch circuits in a compact footprint
