FUSIBLE LINKS AND FUSE ELEMENTS
Fusible links are divided into two categories: the fuse element cartridge and the fusible link. The construction and function of fusible links and fuse elements are similar to that of a fuse. The main difference is that the fusible link and fuse element are used to protect higher amperage electrical circuits, generally circuits 30 amps or more. As with fuses, once a fusible link or fuse element blows out, it must be replaced with a new one.
