20 MFD uf ± 5% MFD 370 V VAC or 440 Volt Multi-Purpose Motor Run Round Capacitor

20 MFD uf ± 5% MFD 370 V VAC or 440 Volt Multi-Purpose Motor Run Round Capacitor

Key Features

• Capacitance: 20 Microfarad (MFD)
• Tolerance: ±5%
• Voltage Rating: Dual 370V or 440V AC
• Frequency: 50/60 Hz
• Shape: Round
• Terminal Type: 1/4 inch male quick-connect
• Operating Temperature Range: -40°C to +70°C

Replaces / Cross-Reference Part Numbers

• Replaces any single-value 20 MFD round run capacitor with a 370V or 440V rating.
• Commonly replaces parts with numbers such as C320, C420, PRCF20, CBB65, and 97F series.

Compatibility & Fitment

• Suitable for use in single-phase motors, HVAC systems, air conditioners, heat pumps, compressors, and fan motors.
• The dual voltage rating allows this capacitor to replace both 370 VAC and 440 VAC models.
• Physical dimensions and terminal configuration are designed for broad compatibility with original equipment.

When to Replace

• Motor hums but does not start.
• Compressor or fan motor runs intermittently or overheats.
• Visible damage to the existing capacitor, such as swelling, bulging, or leaking oil.
• Capacitance measurement is outside the component's rated tolerance (±5%).

Installation Tips

• Disconnect all electrical power to the unit before beginning service.
• Safely discharge the existing capacitor by shorting the terminals with a properly insulated tool.
• Confirm the MFD rating and voltage of the new capacitor match the unit's requirements.
• Note the wire positions on the original capacitor's terminals before removal to ensure correct installation.
