Product Features & Fitment

This motor features a permanent split capacitor design with automatic overload protection and an 80°C ambient temperature rating. It includes four wires—two for power and two for a 2-prong capacitor connection—and requires a 7.5 MFD, 370V capacitor (Part #7.5DV). The motor supports all-angle mounting with extended thru bolts, making it suitable for condenser, heat pump, and refrigeration applications. It is a 4-in-1 multifit motor replacing 1/6, 1/5, 1/4, and 1/3 HP models.
