Fuses and fuse holders

What type of fuse should I use for my windlass?

The choice of fuse for the windlass depends on the motor's power and the system voltage. Check the current drawn by the motor (indicated on the nameplate) and choose a fuse with a slightly higher amperage. For small windlasses, 30A or 40A fuses are generally used. Always consult the manufacturer's manual for recommended specifications.

How do I know if a fuse is blown?

In blade fuses, you can visually check if the internal filament is broken. In glass fuses, check if the filament is blackened or broken. Fuse holders with LED indicators light up when the fuse is blown, simplifying diagnosis.

Can I use a fuse with a different amperage than the original?

No, it is essential to use fuses with the correct amperage. A fuse with a lower amperage will blow continuously, causing power interruptions. A fuse with a higher amperage may not adequately protect the system, risking damage to components in the event of an overload or short circuit.

What does a resettable fuse mean, and when is it advisable to use it?

A resettable fuse, also known as a PTC (Positive Temperature Coefficient) fuse, interrupts in case of overload but automatically resets once the component's temperature drops below a certain threshold. They are recommended in circuits subject to brief and temporary overloads, such as starter motors or lighting circuits.

Where can I find the correct amperage for a fuse?

The correct amperage for a fuse is generally indicated in the manual of the device or equipment it is intended to protect. Alternatively, you can consult the electrical diagrams of the system or contact a qualified electrician.

What is the difference between a standard fuse and a cartridge fuse?

Standard fuses (blade or glass) are used to protect low-voltage circuits (typically 12V or 24V). Cartridge fuses, on the other hand, are designed to protect high-voltage and current circuits, such as those used for powering inverters or large battery chargers. The choice therefore depends on the characteristics of the circuit to be protected.
