1. An apparatus suitable for use in an air-conditioning system and configured to provide a plurality of selectable capacitance values, comprising:
three capacitive devices housed in a case, wherein a first of the three capacitive devices has a capacitance value of about 2.5 to 5 microfarads, a second of the three capacitive devices has a capacitance value of about 5 to 25 microfarads, and a third of the three capacitive devices has a capacitance value of about 10 to 70 microfarads, each of the three capacitive devices having a first capacitor terminal and a second capacitor terminal;
a cover assembly comprising:
a deformable cover mountable to the case,
three capacitor cover terminals, each of the three capacitor cover terminals corresponding to one of the three capacitive devices and each having three contacts extending from the deformable cover, wherein the deformable cover is configured to displace at least one of the three capacitor cover terminals upon an operative failure of at least one of the three capacitive devices, each capacitor cover terminal comprises a terminal post connecting to a detachable tab,
three insulation structures, wherein each of the three insulation structures is configured to provide insulation for at least one of the three capacitor cover terminals, and
a common cover terminal having at least four contacts extending from the deformable cover, wherein the at least four contacts form a square-shaped arrangement at respective locations where the at least four contacts extend from the deformable cover; and
three conductors, wherein each of the three conductors is configured to electrically connect one of the capacitor cover terminals to a first terminal of a corresponding capacitive device, a second terminal of each of the capacitive devices being connected to the common cover terminal; and
at least three frangible connections between the capacitive devices and the cover terminals being provided by the respective terminal post, detachable tab, and conductor, wherein at least one of the three frangible connections is broken when the respective capacitor cover terminal is displaced.
