Rectorseal usa2235 Dual Run Capacitor 40/5 Mfd 370/440V

Product Description

The RECTORSEAL usa2235 is a round dual run capacitor rated at 40/5 microfarads (MFD) and compatible with 370/440 volt systems. Dual run capacitors serve both the compressor and the fan motor in a single unit, providing the phase shift needed to start and maintain efficient motor operation. This capacitor is a direct-replacement component used in residential and light commercial HVAC equipment. Licensed HVAC technicians install this part during routine capacitor replacement or as part of a system diagnostic repair when a failed capacitor is identified.

This dual run capacitor is suited for split-system air conditioners and heat pumps where a single round capacitor handles both compressor and condenser fan motor duties. The 370/440 volt dual-rated design covers the voltage ranges found in standard residential and light commercial condensing units. Its round form factor is one of the most common configurations in the field, making it a practical stock item for service technicians.

Key Features

• Dual run capacitor supports both compressor and condenser fan motor from a single component
• 40/5 MFD rating covers compressor and fan motor capacitance requirements
• 370/440 volt dual-rated for compatibility across common residential system voltages
• Round form factor matches the most widely used capacitor housing style in HVAC condensing units
• Direct OEM-style replacement suitable for standard capacitor swap service calls

Compatibility

Designed as an OEM-style replacement dual run capacitor for residential and light commercial split-system air conditioners and heat pumps requiring a round 40/5 MFD 370/440 volt capacitor.

Installation Notes

Capacitor replacement is performed by licensed HVAC technicians. Always disconnect and lock out power to the condensing unit before servicing capacitors, and discharge the existing capacitor safely before handling — stored charge can remain even after power is removed. Verify the replacement MFD ratings and voltage rating match the equipment nameplate before installation. Follow applicable local electrical codes and manufacturer wiring diagrams during installation.
