ABSTRACT:
The present invention provides a blown fuse indicator. More specifically, the present invention provides a blown fuse indicator adapted for use with multiple element fuses, which provides a perceivable distinction between a blown fuse due to a current overload and a blown fuse due to a short circuit. To this end, in one embodiment of the present invention, a diagnostic blown fuse indicator is provided for a fuse having both a short circuit element and a current overload element. The indicator includes a short circuit indicator in electrical communication with the short circuit element, wherein the short circuit indicator provides visual indication of a short circuit condition. The indicator also includes a current overload indicator in electrical communication with the current overload element, wherein the current overload indicator provides visual indication of an overload condition.
