35+7.5 uf MFD ±5% 370 or 440 Volt AC CBB65B Dual Run Round Capacitor

35+7.5 uf MFD ±5% 370 or 440 Volt AC CBB65B Dual Run Round Capacitor

Key Features

• Capacitance Rating: 35 + 7.5 Microfarad (MFD)
• Capacitance Tolerance: ±5%
• Voltage Rating: 370VAC or 440VAC
• Frequency: 50/60Hz
• Operating Temperature: -40°C to +70°C
• Shape: Round
• Construction: Aluminum case with three terminals (Common, Fan, Hermetic Compressor)
• Function: Serves as a dual run capacitor, supporting a compressor motor and a fan motor simultaneously.

Replaces / Cross-Reference Part Numbers

• Replaces any brand of round dual run capacitor with matching 35/7.5 MFD capacitance and a voltage rating of either 370V or 440V.
• Compatible replacement for CBB65 and CBB65B type capacitors.
• Ensure the physical dimensions (diameter and height) fit your equipment's mounting bracket. A 440V capacitor can replace a 370V capacitor, but not vice-versa.

Compatibility & Fitment

• Designed for use in residential and commercial HVAC systems, central air conditioners, and heat pumps.
• Powers compressor and fan motors in outdoor condenser units.
• Suitable for various AC motor run applications that require a dual capacitor.

When to Replace

• The fan motor runs, but the compressor does not start.
• The air conditioner or heat pump makes a humming noise but will not start.
• The fan blades need a manual push to begin spinning.
• Visible signs of failure on the existing capacitor, such as a bulging top, swelling, or fluid leakage.

Installation Tips

• Warning: Disconnect all electrical power to the unit before performing service. Stored energy in a capacitor can cause severe electrical shock.
• Safely discharge the old capacitor by shorting across the terminals with an insulated screwdriver.
• Note or photograph the wire connections to the C (Common), FAN, and HERM terminals before disconnecting.
• Connect the wires to the corresponding terminals on the new capacitor.
• Secure the new capacitor with the original mounting strap.
