a simple device for protecting electric circuits from overloads and short circuits. A fuse consists of one or several fuse links, an insulating body, and terminals for connecting the fuse to an electric circuit. Some fuses are filled with quartz sand to provide better cooling of the fuse link and to quench the arc; some have actuation indicators.
