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.
Claims24
An apparatus comprising:
- a capacitor container having a cover;
- a plurality of capacitors received within the container, each of the capacitors having a capacitance value;
- a common terminal mounted on the cover and electrically connected to a common terminal of each of said plurality of capacitors;
- a plurality of capacitance value terminals mounted on the cover and spaced apart from the common terminal and from each other, each capacitance value terminal respectively connected to a capacitor of the plurality of capacitors;
- a relay having contacts capable of being electrically connected and disconnected in response to a monitored condition, at least one of the contacts being capable of connecting to at least one of the plurality of capacitance value terminals;
- and
- a cover insulation barrier mounted to the cover, including a cylindrical portion substantially surrounding the common cover terminal and fins extending radially outwards from the cylindrical portion and deployed between adjacent capacitance value terminals.
