About Automotive Fuses
Optifuse Automotive Fuses
Automotive fuses are electrical devices that shut off electric circuits to protect electrical systems from too much current. The main purpose of an automotive fuse is to prevent damage from occurring from too much current running through the electrical system. Fuses are made from a thin strip of alloy metal such as copper or aluminum that is melted and broken when an electrical current overloads, creating an open circuit. The fuse rating is determined by the thickness of the metal strip, which determines how much current can flow through the device before it trips. Automotive fuses are used to protect important electrical components from a temperature surge or short circuit, and come in a range of sizes and shapes, designed to fit most car models. Automotive fuses can also be used to protect equipment such as RV and boat infotainment systems, on-board computers, and even solar energy systems.
