Description
A blade fuse is a type of electrical fuse used to protect wiring and electrical equipment in vehicles and various low-voltage electronic systems. It is named for its flat, blade-like metal terminals that are inserted into a fuse box or fuse holder. The main function of a blade fuse is to protect circuits from overcurrent by breaking the circuit if the current exceeds a predetermined level. The internal metal strip inside the plastic casing melts when overloaded, effectively interrupting the electrical flow and preventing damage or fire hazards.
Blade fuses are widely used in automotive and marine applications due to their compact size, ease of installation, and clear color-coded ratings. They come in various types and sizes such as mini, standard (ATO/ATC), and maxi blade fuses, each designed for different current ratings and circuit requirements. Color coding and printed amperage values on each fuse make it easy to identify and replace. Their reliability, affordability, and standardization have made them a preferred choice for protecting vehicle electrical systems and other low-voltage applications.
