1. A fuse state indicating system comprising:
- at least one fuse comprising a primary fuse element; and
an indicating circuit proximate said fuse and disassociated from said primary fuse element, said indicating circuit configured to detect an opening of said primary fuse element wherein a circuit path is broken through said primary fuse element, said circuit further configured to transmit an optic signal to a remote location when said opening of said primary fuse element is detected, said signal being transmitted without mechanical actuation of said circuit.

Abstract
A fuse state indicating system includes at least one fuse comprising a primary fuse element, and an indicating circuit proximate the fuse and disassociated from the primary fuse element. The indicating circuit is configured to detect an opening of the primary fuse element wherein a circuit path is broken through the primary fuse element. The circuit is further configured to transmit an optic signal to a remote location when the opening of the primary fuse element is detected, and the signal is transmitted without mechanical actuation of the circuit.

11. A fuse indicating system comprising:
-
a fuse having a primary fuse element and a local fuse state indicator, said local fuse state indicator responsive to an operating condition of said primary fuse element and visually indicating said operating condition of said primary fuse element without utilizing a mechanical indicating element; and
an indicating circuit responsive to a state of said local fuse state indicator, said indicating circuit configured to send an optic signal to a remote location when said local fuse state indicator indicates that said primary fuse element is inoperable. - View Dependent Claims (12, 13, 14, 15, 16, 17)
