Rectorseal usa2211 Run Capacitor 20 Mfd 370/440V

Product Description

The RECTORSEAL usa2211 is a round run capacitor rated at 20 microfarads (MFD) and dual-rated for 370 and 440 volts, designed to support motor starting and running efficiency in HVAC systems. Run capacitors store and release electrical energy to maintain a continuous phase shift in single-phase motors, keeping compressors, condenser fan motors, and blower motors running smoothly and at proper torque. This capacitor is a common replacement component installed by licensed HVAC technicians during preventive maintenance or component failure calls.

The usa2211 is suited for residential and light commercial HVAC applications where a round-style run capacitor is required. Its dual voltage rating of 370 and 440 volts makes it compatible with a range of single-phase motor circuits found in split systems, package units, and heat pumps. Technicians typically reach for this capacitor when diagnosing hard-starting compressors, slow-starting condenser fan motors, or motors drawing elevated amperage due to a failed or degraded capacitor.

Key Features

• 20 MFD capacitance rating for precise motor run support
• Dual-rated for 370 and 440 volts, covering a wide range of single-phase HVAC motors
• Round form factor for straightforward mounting in standard capacitor brackets
• Suitable for compressor, condenser fan, and blower motor circuits

Compatibility

Designed as an OEM-style replacement for round run capacitors in residential and light commercial single-phase HVAC equipment requiring 20 MFD at 370 or 440 volts.

Installation Notes

Installation should be performed by a licensed HVAC technician. Always disconnect and lock out power to the unit before handling capacitors, as run capacitors can retain a dangerous charge even after power is removed — discharge the capacitor through a resistor before touching terminals. Verify that the replacement MFD rating and voltage rating meet or exceed the original equipment specification before installing. Follow all applicable local electrical codes and manufacturer wiring diagrams during replacement.
