1. A holder for an electric fuse, the fuse having a pair of spaced electrical terminals, the holder comprising:
- a mounting base formed from a dielectric material;
first means, carried by said base, for electrically conductively cooperating with one of the fuse'"'"'s electrical terminals and for electrically conductively cooperating with a first external conductor;
second means, carried by said base, for electrically conductively cooperating with the other of the fuse'"'"'s electrical terminals and for electrically conductively cooperating with a second external conductor;
said first means and said second means together defining the current path through said fuse holder when an electric fuse is in cooperating relationship therewith; and
,current sensor means carried by said holder at a location where it will be electromagnetically coupled with the magnetic field surrounding at least a portion of said current path when electric current is passing along said current path and for generating an electrical signal responsive to said electromagnetic coupling.

Abstract
A holder for an electric fuse is provided with apparatus which senses the flow of electric current along the current path of the fuse holder, and, which responsive to such sensing, electromagnetically induces an ascertainable signal. The signal may be detected and processed to provide an indication of whether current is flowing through the fuse holder.

10. A holder for an electric fuse, the fuse having a pair of spaced electrical terminals, the holder comprising:
-
a mounting base formed from a dielectric material; a fuse clip mounted on said base for electrically conductively cooperating with one of the fuse'"'"'s electrical terminals; a connector means mounted on said base for electrically conductively cooperating with a first external conductor; means for electrically interconnecting said fuse clip and said connector means; means, carried by said base, for electrically conductively cooperating with the other of the fuse'"'"'s terminals and for electrically conductively cooperating with a second external conductor; and
,current sensor means comprising an inductive pickup means, carried by said mounting base in close proximity to said means for electrically interconnecting said fuse clip and said connector means for, generating an electric signal responsive to the flow of current through said means for interconnecting. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
