ABSTRACT:
Apparatus is provided for automatically interrupting current in an electrical circuit before the first current peak which occurs after an excess current condition develops. The apparatus includes a main conductor in the current path which passes the current under normal operating conditions, and pyrotechnic charge means associated with the conductor at several spaced locations which segments the conductor when it is ignited. The charge means is ignited by a fuse link which senses the current and provides a rapid thermal response to excess current conditions, generating sufficient heat to ignite the charge means within a short period of time. A current limiting fuse element may be connected in parallel with the conductor for operation at higher voltages, if needed, and the entire apparatus, including the resistive sensing means, may be contained in a single housing.
