<p>An electric fuse link (10), which is preferably a cartridge fuse with a cylindrical ceramic body (11) with metal end caps (12), has means for indicating burning out of the fuse element. This consists of a conductive deposit (13) in parallel with the fuse element, but of higher resistance. This is preferably covered by a nonconductive deposit (14) of light colour which prevents arcing and highlights burn-out of the conductive deposit when the element blows.</p> |
