Rectorseal M12047 Dual Run Capacitor 75/10 Mfd 440V

Product Description

The RECTORSEAL M12047 is a dual run capacitor rated at 75/10 microfarads (MFD) and 440 volts, designed for use in residential and light commercial HVAC systems. Run capacitors store and release electrical energy to keep compressor and fan motors running at peak efficiency. This round capacitor serves both the compressor and the condenser fan motor simultaneously, making it a direct-replacement component for service technicians performing capacitor swaps on air conditioners and heat pumps. Its compact round form factor fits standard condenser unit capacitor brackets and simplifies single-unit replacement of a failed dual capacitor assembly.

This capacitor is suited for split-system air conditioners, heat pumps, and packaged units where a dual run capacitor supports both the compressor motor and the outdoor fan motor. It is typically installed during preventive maintenance or after a hard-start fault, motor hum, or failed-to-start diagnosis. HVAC service technicians installing this part should verify MFD ratings match the motor nameplate specifications before installation. The 440-volt rating provides a safety margin on standard 240-volt single-phase residential equipment.

Key Features

• Dual rating of 75/10 MFD supports both compressor and condenser fan motor from a single unit
• 440-volt rating provides operating headroom on standard 240-volt single-phase systems
• Round form factor fits common condenser unit capacitor mounting brackets
• Compact dimensions of 2.5 inches diameter and 5.25 inches height ease installation in tight electrical compartments

Compatibility

Designed as an OEM-style replacement dual run capacitor for residential and light commercial split-system air conditioners and heat pumps requiring a 75/10 MFD, 440-volt round capacitor.

Installation Notes

Installation of run capacitors should be performed by a licensed HVAC technician. Disconnect and lock out all power to the unit before opening the electrical compartment, and discharge any stored voltage in the existing capacitor before handling. Verify that the replacement MFD ratings match the compressor and fan motor nameplates exactly. Follow all applicable NEC requirements for low-voltage electrical component replacement in HVAC equipment.
