Rectorseal M12232 Round Run Capacitor 10 Mfd 440V

Product Description

The RECTORSEAL M12232 is a round run capacitor rated at 10 microfarads (MFD) and 440 volts, designed to support the continuous operation of single-phase motors in HVAC equipment. Run capacitors maintain a phase shift in motor windings during normal operation, improving torque and efficiency. This unit is sized for compressor or fan motor circuits where a compact round form factor is required. Licensed HVAC technicians typically install and service run capacitors during seasonal maintenance calls, compressor replacements, or motor troubleshooting procedures.

This capacitor is suited for residential and light commercial HVAC applications, including central air conditioning systems, heat pumps, and condenser units that use single-phase motors. Its 440-volt rating provides headroom above standard 370-volt applications, making it a commonly stocked replacement value across a range of motor circuits. The compact round body measures 1.75 inches in diameter and 3.125 inches in height, fitting into tight electrical compartments in most standard condenser cabinets.

Key Features

• 10 MFD capacitance for single-phase motor run circuit support
• 440-volt rating suits both 370V and 440V motor applications
• Round form factor fits standard capacitor mounting brackets
• Compact dimensions: 1.75 inches diameter, 3.125 inches height
• Direct OEM-style replacement for common residential and light commercial HVAC motors

Compatibility

Designed as an OEM-style replacement run capacitor for single-phase compressor and fan motors in residential and light commercial HVAC systems requiring a 10 MFD, 440-volt round capacitor.

Installation Notes

Run capacitors must be installed by a qualified HVAC technician. Always disconnect and lock out power to the unit before servicing the capacitor compartment. Capacitors can retain a dangerous charge even after power is removed — discharge the capacitor using an approved resistor tool before handling. Verify the MFD rating and voltage rating on the replacement unit match or exceed the original equipment specification before installation.
