Rectorseal m14126 Dual Run Capacitor 10 Mfd 440/370V

Product Description

The RECTORSEAL m14126 is a dual-section motor run capacitor in a round form factor, designed for use in single-phase HVAC motors that require two capacitance sections in a single housing. Rated at 10 microfarads (MFD) and compatible with both 440-volt and 370-volt circuits at 50 or 60 Hz, this capacitor supports the start and run windings of compressor and fan motor combinations. It is typically installed by licensed HVAC technicians during routine capacitor replacements or system-level repairs on residential and light-commercial cooling equipment.

This dual-section run capacitor suits applications where a single round capacitor serves both the compressor motor and the condenser fan motor simultaneously. The 440/370-volt dual-voltage rating allows it to function across a range of equipment voltages commonly found in residential split systems and packaged units. Its round housing is compatible with standard capacitor mounting brackets used in most condensing unit configurations.

Key Features

• Dual-section design combines two capacitance functions in one round housing
• 10 MFD capacitance rating supports both compressor and fan motor windings
• Dual-voltage rated at 440/370 volts for broad equipment compatibility
• Operates at 50 Hz and 60 Hz for domestic and export system use
• Round form factor fits standard condensing unit capacitor mounting brackets

Compatibility

Designed as an OEM-style replacement dual run capacitor for single-phase residential and light-commercial HVAC condensing units requiring a 10 MFD, 440/370-volt round-style dual capacitor.

Installation Notes

Capacitor replacement is performed by licensed HVAC technicians. Always disconnect and lock out power to the condensing unit before handling capacitors, and discharge the existing capacitor fully before removal, as capacitors store a lethal charge even after power is cut. Confirm that the replacement MFD rating and voltage rating match the equipment nameplate before installation. Follow all applicable local electrical codes and the equipment manufacturer's service documentation during the replacement procedure.
