Abstract: A protection device for an electrical circuit comprises a housing assembly, a fuse support structure that is comprised of a conductive material and that can be coupled to the housing assembly, a main fuse that can be mounted to the fuse support structure to receive a flow of current therefrom and a trip fuse mechanically mounted to the main fuse by electrical contacts. The electrical contacts not only secure the trip fuse to the main fuse, but also provide a conductive path across the main fuse and through the trip fuse. In some embodiments, a momentary switch may be coupled to the trip fuse. In such instances, the trip fuse is configured to activate the momentary switch when a predetermined excessive current flows through the trip fuse and may be electrically connected to a current indicator that indicates when the excessive current flows through the trip fuse.
