Power distribution directly at the source

The Blue Sea BS 5023 fuse block simplifies the wiring of additional onboard consumers. Instead of having to run long cable routes to a central fuse box, this block is mounted directly onto the battery's positive stud (M10). This not only saves valuable space but also ensures the shortest possible cable paths and minimal voltage drops. It is the ideal solution for professionally and securely fusing accessories such as bilge pumps, radios, stereo systems, or fishfinders directly at the battery.

Blue Sea BS 5023 - Compact design with maximum safety

The fuse block holds up to four standard blade fuses (ATO/ATC) and can manage a total current of an impressive 100 Amps. The individual outputs are rated for currents up to 30 Amps. The consumer cables are connected via high-quality #8-32 screw terminals, which are factory-equipped with captive star washers. This guarantees a secure and firm contact even during heavy vibrations at sea or while underway.

Included in the scope of delivery is a custom-fit, insulating polycarbonate cover, which reliably prevents accidental short circuits. On the top of the cover are smart recessed areas where the individual circuits can be clearly labeled using optional Blue Sea format labels.

The main advantages of the Blue Sea BS 5023 at a glance:

• Direct mounting: Bolted directly onto the battery terminal (M10) – saves space and installation effort.
• 4 fused circuits: Uses widely available and easy-to-replace ATO/ATC fuses.
• High capacity: Up to 100A total load at max. 32V DC, perfect for 12V and 24V electrical systems.
• Vibration-proof connection: Screw terminals with integrated star washers for secure holding of cable lugs.
• Secure insulation: Included cover protects against short circuits and provides space for labels.
