## 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.
