Abstract
A polymer-encased capacitor with a nicked-wire interruption system has a capacitor element assembled onto a longitudinally-telescoping support member and installed in a polymer case so that one longitudinal end of the assembly rests on a surface of the case and the other longitudinal end is adjacent a retainer disk spaced at a predetermined longitudinal dimension between a point on the case and the cover of the case. A nicked-wire is attached to the capacitor element, protrudes through the retainer disk and is attached to an electrical terminal on a movable portion of the cover responsive to overpressure conditions in the case.
