The safe marine battery terminal block utilizes a battery house output fuse, which is secure, compact, easy to carry and use, and can save significant installation space. The primary material of the waterproof fuse holder is thermal performance phosphor copper-nickel plating, offering high temperature resistance and wear resistance. The stainless steel bolts and nuts provide good conductivity and strong oxidation resistance. This precision-designed fuse holder prevents accidental short circuits, dust ingress, and minimizes environmental impact on the fuse holder's performance. The waterproof cover on the terminal installation fuse box kit enhances rust protection for increased durability. The package includes 1 terminal fuse box, 1 red insulating cover, 1 washer, 1 lock washer, and 1 hex nut. Widely used battery terminals are commonly applied for circuit protection of DC main power sources in new energy vehicles, RVs, cruise ships, cranes, batteries, charging stations, anchor winches, and bow thrusters.
