Fuses and Fuse Blocks

In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. It essential component is a metal wire or strip that melts when too much current flows through it, thereby stopping or interrupting the current. It is a sacrificial device. The fuse blocks contain fuses rated at different amperage values depending upon the electrical device that it is protecting.
