Rectorseal m12791 Dual Run Capacitor 50/7.5 Mfd 440V

Product Description

The RECTORSEAL m12791 is a dual run capacitor rated at 50/7.5 microfarads (MFD) and 440 volts, designed to support both the compressor and the fan motor in a single round housing. Run capacitors maintain the phase shift needed to keep AC motors running efficiently after startup. This capacitor is sized for residential and light commercial air conditioning equipment and is typically installed by licensed HVAC technicians during seasonal maintenance or compressor and blower motor service calls.

This dual run capacitor fits round-style mounting configurations common in split-system air conditioners and heat pump condensing units. The 50 MFD side serves the compressor motor and the 7.5 MFD side serves the condenser fan motor. Its compact round form factor measures 2.0 inches wide by 3.25 inches tall, making it straightforward to fit into standard capacitor brackets in condensing unit panels.

Key Features

• Dual-rated at 50/7.5 MFD to support compressor and condenser fan motor from a single unit
• 440-volt rating provides a safety margin above standard 370-volt and 440-volt residential AC equipment
• Round housing style fits standard capacitor mounting brackets in condensing units
• Compact dimensions: 2.0 inches wide by 3.25 inches tall

Compatibility

Designed as an OEM-style replacement dual run capacitor for residential and light commercial split-system air conditioners and heat pump condensing units requiring a 50/7.5 MFD 440-volt round capacitor.

Installation Notes

Capacitor replacement is performed by licensed HVAC technicians. Always disconnect and lock out power to the condensing unit before opening the electrical panel. Capacitors store a charge even after power is removed and must be safely discharged before handling. Verify the MFD ratings and voltage rating on the existing capacitor before installing the replacement.
