Rectorseal usa2233 Dual Run Capacitor 45/7.5 Mfd 370/440V

Product Description

The RECTORSEAL usa2233 is a round dual run capacitor rated at 45/7.5 microfarads (MFD) and compatible with both 370 and 440 volt systems. Dual run capacitors serve two motor windings simultaneously, providing start and run support to both the compressor and the condenser fan motor in a single housing. This design reduces the number of components in the electrical panel and simplifies field replacement. Licensed HVAC technicians install this capacitor as a direct service part in split-system air conditioners and heat pumps during routine maintenance or component failure calls.

The usa2233 is suited for residential and light commercial HVAC applications where a round dual run capacitor is specified. The 370/440 volt dual rating gives it broad applicability across a range of equipment manufactured to either voltage standard. Its 45/7.5 MFD configuration matches the most common compressor-and-fan capacitor pairings found in central air conditioning systems. This capacitor is installed inside the outdoor condensing unit, typically housed in the control compartment accessible by removing the unit side panel.

Key Features

• Dual run capacitor supports both compressor and condenser fan motor from a single unit
• 45 MFD compressor winding and 7.5 MFD fan winding in one round housing
• Rated for 370 and 440 volt systems for wide equipment compatibility
• Round form factor fits standard capacitor brackets and clamps used in most condensing units

Compatibility

Designed as an OEM-style replacement dual run capacitor for residential and light commercial split-system air conditioners and heat pumps requiring a 45/7.5 MFD, 370/440 volt round capacitor.

Installation Notes

Dual run capacitors must be installed by a qualified HVAC technician. Disconnect and lock out all power to the condensing unit before opening the control compartment. Capacitors store a charge even after power is removed, so discharge the existing capacitor safely before handling. Confirm the MFD ratings and voltage rating on the existing capacitor match the replacement before installation.
