Patent ID: 7952854

Claim:
A system providing a plurality of selectable capacitance values, the system comprising: an electrolytic capacitive element having a plurality of capacitor sections each having a capacitance value, the capacitor sections each having a capacitor section terminal at a first end and the electrolytic capacitive element having a common element terminal at a second end; a plurality of insulated capacitor section wires each connected at one end to a respective section terminal of one of the plurality of capacitor sections, and an insulated common conductor connected at one end to the common element terminal of the capacitor element; a case having a side wall, a bottom wall and an open top, the electrolytic capacitive element and the insulated wires and insulated conductor connected thereto received in the case with the common element terminal adjacent to and insulated from the bottom wall thereof; a pressure interrupter cover assembly including: a deformable cover having a peripheral edge sealingly secured to an upper end of the case, a common cover terminal mounted to the deformable cover generally at the center of the cover, the common cover terminal having a contact extending upwardly from the cover and a terminal post extending downwardly from the cover to a distal end, a plurality of capacitor section cover terminals mounted to the deformable cover at spaced apart positions generally surrounding the common cover terminal, each capacitor section cover terminal having at least two contacts extending upwardly from the cover and a terminal post extending downwardly from the cover to a distal end thereof; and connections connecting the terminal post of the common cover terminal to the conductor extending from the common element terminal, and connections respectively connecting the plurality of capacitor section wires to a corresponding terminal post of the plurality of capacitor section cover terminals; such that selectable capacitance values are provided by connecting selected cover terminals to place the corresponding capacitor sections in one or more electric circuits and wherein failure of the electrolytic capacitive element causes the deformable cover to deform.
