ANL Gold-Plated Fuses (50 A–500 A High-Current)

These ANL gold-plated fuses are specifically engineered for high-current applications on board. Thanks to their gold-plated fuse blades, they provide superior contact and lower resistance – critical when hundreds of amps are flowing. The gold plating also protects against corrosion in marine environments, ensuring a long service life even in damp conditions. Each fuse is high-capacity and meets the requirements for safeguarding powerful electric motors – ideal for windlasses, bow thrusters, main battery feeds, inverters, and other heavy-load systems.

The wide amperage range (50 A to 500 A) allows you to choose a fuse tailored to your specific equipment and nominal current. For example, a 130 A fuse suits small thrusters or smaller electric anchor winches; 250 A – 325 A fuses cover mid-range thrusters (e.g. 5 kW – 8 kW units) or high-power windlasses; 400 A – 500 A fuses are used for very large systems (such as 10 kW thrusters or main power distribution on luxury yachts). Using the correct amperage fuse ensures that in case of overload or short circuit, your expensive equipment is protected – the fuse will blow and safely break the circuit.

These ANL fuses conform to standard physical size and can be installed in common ANL fuse holders (for instance, model Osculati 14.100.41) designed for high-current fuses. Installation is straightforward – the fuse is secured with nuts in the holder, providing a solid connection. Always mount the fuse as close to the power source (battery) as possible for optimal line protection. With these premium fuses, you can be confident that your boat’s electrical systems are safeguarded beyond usual standards, outperforming generic competitor products.
