Rectorseal usa2240 Dual Run Capacitor 55/5 Mfd 370/440V

Product Description

The RECTORSEAL usa2240 is a round dual run capacitor rated at 55/5 microfarads (MFD) and compatible with both 370-volt and 440-volt AC systems. Dual run capacitors serve two motor windings simultaneously, supporting both the compressor and the condenser fan motor from a single component. This capacitor is a standard replacement part installed by HVAC technicians during routine maintenance or when a failed capacitor is diagnosed as the cause of compressor or fan motor starting issues. The round form factor fits a wide range of residential and light commercial condensing units.

This capacitor is suited for split-system air conditioners and heat pumps where a single round dual run capacitor powers both the compressor and the outdoor fan motor. It is a common replacement item in residential HVAC service work, particularly during cooling season when capacitor failures spike due to heat and load cycles. The 370/440-volt dual rating provides flexibility across the range of single-phase residential condensing units in the field.

Key Features

• Dual run design supports compressor and condenser fan motor from one capacitor
• 55/5 MFD rating covers compressor and fan motor winding requirements
• Dual voltage rating 370/440 volts fits a broad range of single-phase residential equipment
• Round form factor for easy drop-in replacement in standard capacitor brackets

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 55/5 MFD 370/440-volt capacitor.

Installation Notes

Dual run capacitors are replaced by licensed HVAC technicians. Always disconnect and lock out power to the condensing unit before handling capacitors, as they store a charge that can remain present even after power is removed. Discharge the capacitor using an appropriately rated discharge tool before disconnecting leads. Verify the replacement MFD ratings and voltage rating match the failed component before installing.
