ABSTRACT:
A multisection AC capacitor having a pressure sensitive fault interrupter, said capacitor being a dry metallized AC motor start and motor run capacitor, said fault interrupter having a dome shaped diaphragm secured to one electrode at the base of one capacitor section within said unit and one or more core connectors spatially separating and securing said capacitor sections within a sleeve such that the multisection stacked capacitor may be potted within a case and gases resulting from a build up of pressure within said capacitor will be directed to its core and downward therefrom to exert pressure, causing the dome of the diaphragm to be depressed, thereby breaking the electrical contact of one electrode, thus isolating the capacitor from its power supply.
