Detailed description

Designed to simplify the addition of electrical circuits, the BLUE SEA 5024-BSS ST Blade fuse block kit for battery terminal mounting allows you to easily integrate up to four protected circuits directly on a battery terminal. This compact and efficient solution is intended to power new accessories on your boat or vehicle without requiring complex modifications to existing wiring.

Integration and Protection

The fuse block mounts directly onto the battery terminal stud, with compatibility for 3/8" (M10) studs. It features #8-32 screw terminals with captive washers for secure wire connections. The 5024-BSS kit differs from the 5023 model (block only) by including four insulated nylon ring terminals for 16-14 AWG wires and four for 12-10 AWG wires, as well as four writable labels to identify the circuits. Protection is provided by an insulating cover compliant with ABYC/USCG requirements, and the system is ignition protected per ISO 8846 and SAE J1171 standards, making it suitable for gasoline engine compartments.

Technical Specifications and Compatibility

This block supports a maximum voltage of 32V DC and a maximum current of 100A for the entire block, with a maximum of 30A per circuit. It is compatible with ATO or ATC type fuses (sold separately). The internal bus is made of tinned copper C11000, ensuring optimal conductivity and corrosion resistance. For larger or more complex electrical distribution needs, BLUE SEA offers alternative solutions such as the 2340 busbar range, while the 5024-BSS remains a dedicated option for simple and secure extension of auxiliary circuits from the main battery.

Expert opinion

« Compact electrical distribution solution for accessories »

The ST Blade BLUE SEA 5024-BSS fuse block kit is a direct and reliable electrical extension solution, particularly relevant for owners of small and medium boats, as well as recreational vehicles. It allows adding up to four auxiliary circuits, such as powering a secondary VHF, a fishfinder, cockpit lighting, or USB outlets, without disrupting the main distribution panel wiring.

Its mounting on the battery stud (M10) is a major advantage, as it minimizes cable length and simplifies installation, reducing potential voltage drops. The inclusion of insulated ring terminals and circuit labels in the 5024-BSS kit, unlike the standalone 5023 block, saves time and provides convenience for the installer. Compliance with ABYC/USCG standards and spark-proof protection are essential features, ensuring safe use in gasoline engine compartments—a factor often overlooked but critical.

This product excels in scenarios where isolated circuit extensions are required near the battery. It is not designed to replace a main distribution panel or handle very high-power circuits. For installations requiring more than four circuits or centralized circuit management, it is advisable to opt for more advanced distribution systems from the BLUE SEA range or other manufacturers.

How is the fuse block mounted on the battery?

The fuse block is mounted directly on the battery terminal stud. It is designed for a 3/8" (M10) stud clearance.

What types of terminals are used to connect the wires?

Type #8-32 screws with captive washers are used to secure wires.

What are the main steps to install this fuse block?

Mount the fuse block on the battery terminal stud (3/8" or M10). Connect the wires from your accessories to the #8-32 screw terminals, using the supplied insulated ring terminals if necessary. Insert the appropriate ATO or ATC fuses (sold separately) for each circuit. Use the supplied writable labels to identify each circuit. Ensure the insulating cover is correctly installed.

Is it necessary to use the provided ring terminals?

Nylon insulated ring terminals are included for each screw terminal to facilitate secure wire connections. Their use is recommended for optimal installation, but necessity may depend on the type of wire used.
