An automotive fuse is a safety device that protects the electrical system of a vehicle from damage caused by excessive current. It is a small, cylindrical component made of metal and plastic, and it is designed to melt or blow out when the current flowing through it exceeds its rated value. This action breaks the circuit and prevents further damage to the electrical components.Automotive fuses are typically rated in amperes (A) and are color-coded to indicate their current rating. They are commonly used in various parts of a vehicle's electrical system, including the engine compartment fuse box, interior fuse box, and fuse panels for specific components such as headlights, radio, and power windows.
