Rectorseal m12866 Dual Run Capacitor 70/7.5 Mfd 440V

Product Description

The RECTORSEAL m12866 is a dual run capacitor rated at 70/7.5 microfarads (MFD) and 440 volts, designed for use in single-phase HVAC compressor and fan motor circuits. Dual run capacitors serve two motor windings simultaneously, providing the phase shift needed for start and continuous run operation. This round-style unit measures 2.0 inches wide by 4.375 inches tall, making it a compact, space-efficient replacement for failed or degraded capacitors in split-system air conditioners and heat pumps. Licensed HVAC technicians are the typical installers for this component.

This capacitor is suited for residential and light commercial HVAC applications where a single round capacitor powers both the compressor and the condenser fan motor. Round dual run capacitors are a standard configuration found in a wide range of split-system condensing units. It is appropriate for use in equipment calling for a 70/7.5 MFD dual run capacitor at a 440-volt rating.

Key Features

• Dual run capacitor serves both compressor and fan motor from a single round unit
• 70/7.5 MFD rating covers a common compressor and fan motor pairing
• 440-volt rating provides compatibility with standard single-phase condensing unit circuits
• Round form factor fits most standard capacitor brackets and mounting clips
• Compact dimensions: 2.0 inches wide by 4.375 inches tall

Compatibility

Designed as an OEM-style replacement dual run capacitor for residential and light commercial split-system air conditioners and heat pumps requiring a 70/7.5 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 servicing. Capacitors store a lethal electrical charge even after power is removed — discharge the capacitor through an appropriate resistor before handling terminals. Follow NEC guidelines for electrical component replacement in HVAC equipment.
