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.
Claims20
An apparatus comprising:
- a container capable of receiving a plurality of capacitive devices, each of the capacitive devices having a first capacitor terminal and a second capacitor terminal;
- a cover mountable to the container, the cover comprising:
- 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;
- and
- a plurality of insulation structures, each insulation structure associated with one of the plurality of capacitor cover terminals;
- a plurality of first conductors, each first conductor electrically connectable 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 electrically connectable to each of the second capacitor terminals of the plurality of capacitive devices and the common cover terminal;
- and
- a relay having contacts and being capable of opening said contacts in response to a condition,
- wherein the relay is sized to fit above the container and to fit within a cylindrical envelope being projected from the container, and wherein the relay sized to fit within the cylindrical envelope being projected from the container is coverable by a cap of the container.
An apparatus comprising:
- a container capable of receiving at least four capacitive devices, each of the capacitive devices having a first capacitor terminal and a second capacitor terminal;
- a cover mountable to the container, the cover comprising:
- a common cover terminal having at least one contact extending from the cover;
- at least four capacitor cover terminals, each of the at least four capacitor cover terminals having at least one contact extending from the cover;
- and
- at least four insulation structures, each insulation structure associated with one of the plurality of capacitor cover terminals;
- at least four first conductors, each first conductor electrically connectable to one of the first capacitor terminals of the at least four capacitive devices and one of the at least four capacitor cover terminals;
- a second conductor electrically connectable to each of the second capacitor terminals of the at least four capacitive devices and the common cover terminal;
- and
- a relay having contacts and being capable of opening said contacts in response to a condition,
- wherein the relay is sized to fit above the container and to fit within a cylindrical envelope being projected from the container, and wherein the relay sized to fit within the cylindrical envelope being projected from the container is coverable by a cap of the container.
