Rectorseal usa2238 Dual Run Capacitor 50/7.5 Mfd 370/440V

Product Description

The RECTORSEAL usa2238 is a round dual run capacitor rated at 50/7.5 microfarads (MFD) and 370/440 volts, designed for continuous-duty operation in HVAC and refrigeration equipment. Dual run capacitors support both the compressor and the condenser fan motor from a single unit, reducing component count and simplifying wiring. The usa2238 uses a metallized film, non-PCB dielectric fluid construction and carries a 60,000-hour operational life rating. Its temperature range spans -40 to 70 degrees C, making it suitable for the wide ambient swings typical in rooftop and outdoor condensing unit applications. Licensed HVAC technicians are the primary installers for this component.

The usa2238 is rated for residential and commercial air conditioning and refrigeration systems. It is compatible with 50 Hz and 60 Hz equipment, which covers the full range of domestic installations as well as select international or export-spec units. The round form factor fits standard capacitor brackets and round capacitor housings found in most outdoor condensing units and packaged rooftop systems. Where a failed or out-of-tolerance dual run capacitor is diagnosed, the usa2238 serves as a direct replacement in applications requiring 50/7.5 MFD at 370 or 440 volts.

Key Features

• Dual capacitance — 50 MFD for compressor, 7.5 MFD for condenser fan motor
• Dual voltage rating: operates at 370 or 440 volts
• Metallized film construction with non-PCB dielectric fluid
• 60,000-hour operational life rating for extended service intervals
• Wide temperature range: -40 to 70 degrees C
• Rated for both 50 Hz and 60 Hz systems
• Round shape fits standard condensing unit capacitor brackets

Compatibility

Designed as a replacement dual run capacitor for residential and commercial air conditioning and refrigeration equipment requiring a 50/7.5 MFD, 370/440-volt round capacitor.

Installation Notes

Capacitor replacement is performed by a licensed HVAC technician. Disconnect and lock out all power to the unit before opening the electrical compartment, and discharge the existing capacitor through a resistor before handling — stored charge can remain present even after power is removed. Verify MFD rating, voltage rating, and terminal configuration match the original capacitor before installation. Follow NEC requirements for disconnect and wiring practices applicable to the equipment being serviced.
