• Tolerance: ±5%
• Voltage Rating: Dual rated for 370V or 440V AC
• Frequency: 50/60Hz
• Model: CBB65
• Shape: Oval
• Construction: Oil-filled metallized polypropylene film
• Safety: Integrated pressure-sensitive interrupter
• Terminals: Standard 1/4 inch male terminals

Replaces / Cross-Reference Part Numbers

Replaces any single-value, oval-shaped run capacitor with identical 10 uF capacitance and 370V or 440V specifications. Serves as a direct replacement for CBB65 and CBB65A models with matching ratings.

Compatibility & Fitment

Designed for continuous duty in a variety of motor-run applications:

• Air conditioner condenser fan motors
• Heat pump compressors and fan motors
• Furnace blower motors
• Pool and spa pump motors
• Other single-phase AC electric motors

When to Replace

Replacement may be necessary if you observe the following symptoms:

• Motor hums but does not start
• Fan or motor requires a manual push to start
• AC unit compressor fails to engage
• Unit runs intermittently or blows warm air
• Visible bulging, cracking, or fluid leakage from the capacitor case

Installation Tips

• Disconnect all electrical power to the unit before performing any work.
• Safely discharge the existing capacitor by shorting across the terminals with an insulated screwdriver.
• Verify that the uF (MFD) rating matches the original capacitor. The voltage rating can be equal to or higher than the original, but not lower.
• Connect wires to the new terminals. Polarity is not a factor for two-terminal AC capacitors.
• Secure the new capacitor in the original mounting bracket.
