Rectorseal M12049 Oval Run Capacitor 50 Mfd 440V

Product Description

The RECTORSEAL M12049 is a 50 microfarad (MFD), 440-volt oval run capacitor designed for use in single-phase electric motors found in HVAC equipment. Run capacitors maintain a continuous phase shift in the start or run winding of a motor, allowing it to operate at proper torque and efficiency. This unit is rated at 50 MFD and 440 volts, making it suitable for compressor, condenser fan, or air handler fan motor applications. Licensed HVAC technicians install this type of capacitor as a direct replacement when a failed or weakened capacitor causes motor hard-starting, overheating, or failure to run.

This oval run capacitor is used in residential and light commercial HVAC systems where motor starting and running performance must be maintained. Oval-style capacitors are commonly installed in condenser units and air handling equipment where space is a consideration. The 440-volt rating provides compatibility across a range of single-phase motor voltages typically encountered in the field, including 370-volt-rated applications where a 440-volt unit is an accepted substitute.

Key Features

• 50 MFD capacitance rating for correct motor torque and run performance
• 440-volt rating suitable for both 370-volt and 440-volt motor applications
• Oval form factor for installation in space-constrained equipment cabinets
• Dimensions of 1.806 x 2.806 x 5.25 inches fit standard capacitor mounting brackets

Compatibility

Designed as an OEM-style replacement run capacitor for single-phase HVAC motors rated at 50 MFD and up to 440 volts in residential and light commercial systems.

Installation Notes

Run capacitor replacement is performed by licensed HVAC technicians. Always disconnect and lock out power to the unit before servicing capacitors, and discharge the capacitor fully before handling, as stored charge can cause serious injury even after power is removed. Verify the MFD rating and voltage rating of the original capacitor before installing a replacement. Follow all applicable electrical codes and equipment manufacturer guidelines during installation.
