Automotive FusesAutomotive fuses are a type of circuit protection device that is used in vehicles to protect the electrical circuits from damage due to excessive currents. An automotive fuse consists of a strip of metal that melts when a certain level of current flows through it, interrupting the circuit and preventing further current flow. Automotive fuses are available in a variety of sizes and ratings, and are selected based on the current-carrying capacity of the circuit they are protecting. They are commonly used in the electrical systems of cars, trucks, and other vehicles to provide protection against electrical fires and other types of damage.
