The Blue Sea Systems 5056 ST-Blade Water-Resistant Fuse Block with Cover offers reliable circuit protection in harsh environments. Designed to accommodate ATO and ATC fast-acting blade fuses, this fuse block features a compact footprint with a single side nesting design that simplifies wiring by allowing entry from one side. The water-resistant construction ensures durability against moisture, making it suitable for marine, RV, and off-road applications. Its insulating cover meets ABYC and USCG standards, providing an additional layer of protection for your electrical system. The fuse block includes three wire plugs to maintain water resistance when fewer than four loads are connected, and it accepts a wide range of wire sizes from 8 AWG to 4 AWG for input and 16 AWG to 10 AWG for loads. Constructed with tin-plated copper bus bars and fuse clips, it guarantees excellent conductivity and corrosion resistance. The fuse block is compatible with low-profile circuit breakers and nests seamlessly with other water-resistant components, reducing wire clutter and simplifying installation. It features mounting holes that fit 1/4-inch screws and screw terminals with #8-32 screws and captive star lock washers for secure connections. The product also includes four write-on circuit labels, with options for small-format custom labels, and provides spare fuse and fastener storage within the cover for convenience. With an 80-ampere capacity per block and a maximum voltage of 32V DC, the device is ideal for various DC electrical systems, supporting multiple circuits with a maximum of 25A each. Its robust design and thoughtful features make it a trusted choice for demanding electrical setups that require water resistance, ease of wiring, and reliable circuit protection.
