Fuses, acting as vital components in circuit protection, are primarily designed to safeguard electronic devices from damage caused by excessive current or a power surge. They perform this important function by "blowing" or "breaking" when the current surpasses the fuse's defined limit. The basic purpose of a fuse is to act as a safety device, preventing malfunctions or accidents that might arise due to over current situations.
The various applications of fuses span across multiple industries like automotive, consumer electronics, industrial, and power applications, to name a few. One of the significant characteristics of fuses is their sensitivity to overcurrent, leading to their accurate and swift response in breaking the circuit, thus preventing potential hARM or damage. Furthermore, they are generally easy to install and replace, and come in a wide range of sizes and styles to suit different requirements. Notable manufacturers of fuses include Bourns, Eaton, Littelfuse, and Bel Fuse, among others.
