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.
Claims19
An apparatus comprising:
- a container capable of receiving a plurality of capacitive devices, each of the plurality of capacitive devices having a first capacitor terminal and a second capacitor terminal;
- a cover configured to be mounted to the container, wherein the cover comprises:
- a common cover terminal having at least one contact extending from the cover;
- a plurality of capacitor cover terminals, each of the plurality of capacitor cover terminals having at least one contact extending from the cover;
- a plurality of first conductors, wherein each of the plurality of first conductors is configured to electrically connect to one of the first capacitor terminals of the plurality of capacitive devices and one of the plurality of capacitor cover terminals;
- a second conductor configured to electrically connect to each of the second capacitor terminals of the plurality of capacitive devices and the common cover terminal;
- and
- a plurality of insulation structures, wherein each insulation structure is associated with one of the plurality of capacitor cover terminals;
- a magnet positioned external to the container, the magnet including an inner surface and an outside surface opposite the inner surface, wherein the outside surface includes a recess, and wherein the inner surface is curved and configured to interface with an outer surface of the container, wherein the magnet comprises a projection to position the magnet relative to the container;
- and
- a relay positioned external to the container and configured to control opening and closing of contacts, wherein selected ones of the plurality of capacitive devices are electrically connected to equipment external to the container when the contacts are closed.
