About the Mars Blue Box Motor Run Capacitor, 20/4 MFD, Dual Section 370 Volt Round (12207)
Order and save on the Mars 12207 Dual Motor Run Capacitor, 20/4 MFD, 370V, Round from PlumbersStock.com. Motor run capacitors alter the current, creating a rotating magnetic field in single-phase induction motors. The beauty of a dual motor run capacitor is that it can support two motors because it houses two capacitors in one body.
This Blue Box series has a reputation for producing the most reliable motor run capacitors. The initials MFD stand for Microfarad (a millionth of a Farad), which is a measurement of the capacitor's capacity. Mars has made a name for itself by manufacturing reliable heating and cooling products. As the manufacturer describes it, Dual section run capacitors are used primarily to serve two microfarad applications. They can, however, by making various combinations of parallel connections, be used to obtain many other microfarad ratings.
