Replaces / Cross-Reference Part Numbers

• Replaces any round or oval single-value run capacitor with a 50 uF MFD rating and a voltage of 370V or 440V.
• Compatible with CBB65 type capacitors matching these specifications.

Compatibility & Fitment

• Used in single and three-phase motor applications.
• Commonly found in HVAC systems, air conditioners, compressors, heat pumps, and condenser fan motors.
• Suitable for general purpose AC motor run, blower, or fan start applications.

When to Replace

• Motor hums but fails to start or struggles to start.
• Motor runs at a reduced speed or with diminished power.
• Visible signs of failure on the old capacitor, such as bulging, swelling, or fluid leaks.
• Capacitance measurement is outside the specified ± 5% tolerance range.

Installation Tips

• Disconnect all electrical power to the unit before performing installation.
• Safely discharge the existing capacitor by shorting the terminals with an insulated tool.
• Verify that the microfarad (uF/MFD) rating matches the component being replaced.
• The replacement capacitor's voltage rating must be equal to or greater than the original capacitor's rating.
• Ensure all electrical connections are secure.
