668-650

This premium dual run capacitor is a vital component for HVAC systems, designed to provide the necessary electrical boost for both the compressor and the condenser fan motor. Featuring a dual capacitance of 45/10 MFD and rated for use in both 370V and 440V applications, this part ensures reliable start-ups and efficient motor operation. It is a common replacement part for central air conditioners and heat pumps that exhibit symptoms like humming but not starting, or intermittent cooling performance. Engineered for durability and thermal resistance, this capacitor helps maintain the longevity of your cooling system's most expensive components by providing steady power delivery and reducing electrical strain during peak usage.
