Fuses and fuse boxes
Fuse sets, fuses and fuse holders for boat use and other demanding conditions.

In the Fuses and Fuse Holders section you will find the components needed to protect your boat's electrical system: Pro Supply's automatic fuses with various amperage ratings (25A, 30A, 40A, 50A), BEP's Pro Installer fuse holder (750A) and Pro Supply's Mega fuse holder. A properly sized fuse protects the boat's wiring and equipment in the event of a short circuit or overload — a fuse with too high an amperage rating will not trip in time and can lead to overheating of the wires or even a fire. The amperage rating of the fuse should always be sized according to both the power consumption of the device being protected and the cross-sectional area of ??the wire used — the thicker the cable, the larger the fuse it can usually withstand, but the device's own current requirement is always the primary sizing criterion. Take a closer look at our subgroups Fuses, Fuse Holders and Fuse Sets to find the right component for your boat's electrical system — automatic fuses are particularly practical, as they can be reset after tripping without replacing the part.
