Abstract: An apparatus includes a case having an elliptical cross-section capable of receiving a plurality of capacitive elements. One or more of the capacitive elements provide at least one capacitor having a first capacitor terminal and a second capacitor terminal. The apparatus also includes a cover assembly that includes a deformable cover mountable to the case, and, a common cover terminal having a contact extending from the cover. The cover assembly also includes at least three capacitor cover terminals, each of the at least three capacitor cover terminals having at least one contact extending from the deformable cover. The deformable cover is configured to displace at least one of the at least three capacitor cover terminals upon an operative failure of at least one of the plurality of the capacitive elements. The cover assembly also includes at least four insulation structures. One of the four insulation structures is associated with one of the at least three capacitor cover terminals. The apparatus also includes a first conductor capable of electrically connecting the first capacitor terminal of a capacitor provided by one of the plurality of capacitive elements to one of the at least three capacitor cover terminals and a second conductor capable of electrically connecting the second capacitor terminal of the capacitor provided by one of the plurality of capacitive elements to the common cover terminal.

Abstract: A capacitor provides a plurality of selectable capacitance values, by selective connection of six capacitor sections of a capacitive element each having a capacitance value. The capacitor sections are provided in a plurality of wound cylindrical capacitive elements. Two vertically stacked wound cylindrical capacitance elements may each provide three capacitor sections. There may be six separately wound cylindrical capacitive elements each providing a capacitor section. The capacitor sections have a common element terminal. A pressure interrupter cover assembly is sealingly secured to the open end of case for the elements and has a deformable cover with a centrally mounted common cover terminal and a plurality of section cover terminals mounted at spaced apart locations. A conductor frangibly connects the common element terminal of the capacitor section to the common cover terminal and conductors respectively frangibly connect the capacitor section terminals to the section cover terminals. Deformation of the cover caused by failure of the capacitor element breaks at least some of the frangible connections sufficient to disconnect the capacitive element from an electric circuit in which it is connected. A cover insulation barrier mounted on the deformable cover, has a barrier cup substantially surrounding the common cover terminal and a plurality of barrier fins each extending radially outwardly from the barrier cup, and deployed between adjacent section cover terminals.

Abstract: A hard start capacitor replacement unit has a plurality of capacitors in a container sized to fit in existing hard start capacitor space. The capacitors are 4 metallized film capacitors wound in a single cylindrical capacitive element. The container has a common terminal and capacitors value terminals for the plurality of capacitors, which may be connected singly or in combination to provide a selected capacitance. An electronic or other relay connects the selected capacitance in parallel with a motor run capacitor. The hard start capacitor replacement unit is thereby adapted to replace a wide variety of hard start capacitors.
