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 the continuous phase shift needed to keep single-phase induction motors running smoothly after startup. The dual configuration means this single round capacitor serves two motor loads simultaneously, typically the compressor and the condenser fan motor. Licensed HVAC technicians install and replace this component as part of routine system maintenance or when a failed capacitor is causing motor run issues, reduced efficiency, or system lockout.

This capacitor is suited for split-system air conditioners, heat pumps, and package units where a combined 50/5 MFD dual run capacitor is specified. The 370/440 volt dual-voltage rating provides flexibility across a range of equipment. It is a common replacement item during summer service calls when capacitors degrade from thermal cycling and age. The round form factor fits standard capacitor brackets and enclosures found in most condenser unit control compartments.

Key Features

• Dual run configuration supports two motor loads from one capacitor body
• 50/5 MFD rating covers both compressor and condenser fan motor circuits
• 370/440 volt dual-voltage rating suits a wide range of single-phase HVAC equipment
• Round shape fits standard condenser unit capacitor mounting brackets
• Dual connection terminals for straightforward wiring to two separate loads

Compatibility

Designed as an OEM-style replacement dual run capacitor for single-phase residential and light commercial HVAC systems requiring a 50/5 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 unit before accessing the control compartment, and discharge any existing capacitor before handling, as capacitors can retain a dangerous charge even after power is removed. Verify that the replacement MFD and voltage ratings match the equipment nameplate specifications before installation. Follow all applicable local electrical codes and manufacturer wiring diagrams when reconnecting terminals.
