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