Rectorseal M12234 Round Run Capacitor 15 Mfd 440V

Product Description

The RECTORSEAL M12234 is a round run capacitor rated at 15 microfarads (MFD) and 440 volts, designed to support the continuous operation of single-phase motors in HVAC equipment. Run capacitors maintain the phase shift required to keep compressor and fan motors running at rated efficiency after startup. The M12234 round form factor is a widely used configuration in residential and light commercial condensing units and air handlers. Licensed HVAC technicians replace these components as part of routine maintenance or when motor run issues, excessive current draw, or capacitor bulge are confirmed during service.

This capacitor is suited for installation in split-system air conditioners and heat pumps where a single-section round run capacitor is specified. It is commonly installed on condenser fan motors or compressors that call for a 15 MFD, 440-volt round unit. The 440-volt rating provides operating headroom on systems supplied by nominal 208-volt or 240-volt single-phase power.

Key Features

• 15 MFD capacitance rating for single-section motor run applications
• 440-volt rating suitable for 208-volt and 240-volt single-phase systems
• Round form factor for straightforward bracket or strap mounting
• Compact dimensions fit standard capacitor mounting hardware in condensing units

Compatibility

Designed as an OEM-style replacement round run capacitor for residential and light commercial HVAC systems requiring a 15 MFD, 440-volt single-section unit.

Installation Notes

Run capacitors must be installed by a qualified HVAC technician. Disconnect and lock out all power to the unit before handling capacitors, and discharge the existing capacitor through a rated resistor before making contact. Confirm the MFD rating and voltage rating on the original capacitor before replacement. Follow all applicable local electrical codes and manufacturer wiring diagrams when reconnecting terminals.
