ABSTRACT:
The invention is a circuit protection device comprising a first and a second female terminal. The device further comprises a first fuse clip in electrical contact with the first fuse terminal and a second fuse clip in electrical contact with the second fuse terminal. A positive temperature coefficient element, preferably planar, is positioned between and makes electrical contact with both the first fuse clip and the second fuse clip. In a first embodiment, at least one of the first and second fuse clips is spring-loaded, i.e., has an inherent resiliency. In this same embodiment, portions of the first and second fuse clips overlap, and the positive temperature coefficient element is secured between the overlapping portions of the first and second fuse clips. In the second of the two preferred embodiments, the first fuse clip, the second fuse clip, and the positive temperature coefficient element are generally coplanar.
