ABSTRACT:
A pressure sensitive fault interrupter for an oil impregnated metallized AC motor start and motor run capacitor having a dome-shaped diaphragm secured to one contact electrode bridge at the base of the capacitor roll such that a rise in pressure within said roll will cause the dome of said diaphragm to be depressed, thereby breaking electrical contact of one electrode, thus isolating the capacitor from its power supply.
