Rectorseal usa2228 Run Capacitor 70 Mfd 370 440V

Product Description

The RECTORSEAL usa2228 is a round run capacitor rated at 70 microfarads (MFD) and dual-voltage compatible at 370 or 440 volts. Run capacitors provide the continuous phase-shifted current needed to keep single-phase PSC motors spinning efficiently after startup. This unit is installed in the capacitor compartment of the electrical panel on residential and light commercial HVAC equipment. Licensed HVAC technicians replace run capacitors as part of routine seasonal maintenance or when diagnosing motor faults such as hard-starting compressors, condenser fan motors, or air handler blower motors that fail to run at full speed.

The usa2228 is suited for condensing unit compressors and condenser fan motors in split-system and packaged HVAC equipment where a 70 MFD round-style capacitor is specified. The dual 370/440 volt rating makes it adaptable across a wide range of equipment voltage requirements, reducing the need to stock separate capacitors for different unit ratings. It is a common replacement item during cooling season service calls when capacitor failure is confirmed through capacitance testing with a multimeter or dedicated capacitor tester.

Key Features

• 70 MFD capacitance rating for high-demand single-phase PSC motor applications
• Dual-rated at 370 and 440 volts for broad equipment compatibility
• Round form factor fits standard HVAC capacitor brackets and compartments
• Designed as a direct drop-in replacement for failed or degraded run capacitors

Compatibility

Designed as an OEM-style replacement run capacitor for residential and light commercial HVAC systems requiring a 70 MFD 370/440 volt round capacitor.

Installation Notes

Run capacitor replacement should be performed by a licensed HVAC technician. Always disconnect and lock out power to the unit before opening the electrical compartment. Capacitors retain a charge even after power is removed and must be safely discharged before handling. Verify capacitance and voltage ratings match the equipment nameplate specifications before installation.
