A fuse is a safety device that melts and protects the wiring against too high an electric current. Most fuses are hidden in a so-called fuse box. A blown fuse can be recognized by the fact that the metal strip in the fuse has melted through. You remove a fuse with the help of a fuse extractor.
Below you will find various plug-in fuses, in both 'normal' and miniature format and in various amperages, recognizable by the colour codes.
