ABSTRACT:
A fault-indicating blade fuse includes a light-emitting electrical device that is positioned for ready visibility from above the fuse. The device lies within the bounds of the upper body profile of the fuse, and is so constructed and connected as to be activated upon fusion of the link, when the fuse is subjected to excessive current. In one form, a supplemental component contains a light-emitting electrical device and includes means for affixing it to the upper body portion of a fuse. Contact elements on the supplemental component establish electrical contact with the blades of the assembled fuse.
