Description
Product Summary
The Supco CS320-384X220 Start Capacitor, 320-384 MFD, 220V is a professional-grade replacement part from Supco (Sealed Unit Parts Co.), a trusted name in HVAC/R and appliance parts since 1945. SUPCO® capacitors are manufactured with the highest quality components. Our capacitors are manufactured and tested under our high standards and specifications. SUPCO always strives to supply excellent quality products at an economic price.
Start capacitors provide a short, high-capacity boost that gets compressors and motors turning from a dead stop, then drop out of the circuit through a start relay. They are rated for intermittent duty only. Choose a replacement with the same MFD range and an equal or higher voltage rating, and pair it with the correct start or potential relay.
