Run Start Capacitor, Round, 20/7.5 MFD, 440/370

Save on the Mars 12654 Dual Motor Run Capacitor, 20/7.5 MFD, 440V, Round from PlumbersStock. 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. JARD by Mars is a series of quality, low-cost alternative capacitors. The initials MFD stand for Microfarad (a millionth of a Farad), which is a measurement of the capacitor's capacity. Mars is a leader in the industry for obvious reasons. They make great HVAC solutions.
