An auto blade fuse is a type of fuse used in automotive applications. It is a small, rectangular fuse that is designed to protect electrical circuits from overcurrent or short circuits. The blade fuse has two metal terminals on either end, which are inserted into fuse holders or fuse blocks in the vehicle's electrical system. Auto blade fuses come in different current ratings, typically ranging from 1 amp to 40 amps. Each fuse is color-coded to indicate its current rating, making it easy to identify and replace the correct fuse when needed. When an overcurrent or short circuit occurs in the electrical system, the auto blade fuse is designed to break the circuit and prevent damage to the vehicle's wiring or electrical components. Once the fault is resolved, the fuse can be replaced to restore power to the circuit. Auto blade fuses are commonly used in cars, trucks, motorcycles, and other vehicles. They are widely available and relatively inexpensive, making them a popular choice for automotive electrical protection.
