Rectorseal usa2237 Dual Run Capacitor 50/5 Mfd 370/440V

Product Description

The RECTORSEAL usa2237 is a dual run capacitor rated at 50/5 microfarads (MFD) and 370/440 volts, designed for use in residential and light commercial HVAC systems. Run capacitors provide continuous phase-shifted current to motor windings, keeping compressors and fan motors running efficiently after startup. The dual configuration allows a single unit to serve both the compressor and the condenser fan motor simultaneously. This round-style capacitor is a standard replacement component installed by licensed HVAC technicians during routine maintenance or motor failure diagnosis.

This capacitor is suited for split-system air conditioners, heat pumps, and package units where a dual run capacitor is required. The 370/440-volt dual-rated design provides compatibility across a range of equipment operating at either voltage level. It is commonly installed when an existing capacitor shows reduced capacitance, bulging, or fails a capacitance test during a service call.

Key Features

• Dual capacitance rating of 50 MFD and 5 MFD in a single round unit
• Dual voltage rating of 370/440 volts for broad equipment compatibility
• Round shape fits standard capacitor brackets and mounting clips
• Dual connection configuration serves compressor and fan motor circuits simultaneously
• Run capacitor type designed for continuous-duty motor operation

Compatibility

Designed as an OEM-style replacement dual run capacitor for residential and light commercial HVAC systems requiring a round 50/5 MFD 370/440-volt capacitor.

Installation Notes

Capacitor replacement is performed by licensed HVAC technicians. Disconnect and lock out power to the unit before handling any capacitor, as capacitors can retain a dangerous charge even after power is removed — discharge the capacitor safely using an insulated resistor tool before touching terminals. Verify the replacement MFD and voltage ratings match the original equipment nameplate before installation. Follow applicable local electrical codes and the equipment manufacturer's service guidelines.
