Rectorseal M12284 Dual Run Capacitor 35/7.5 Mfd 440V

Product Description

The RECTORSEAL M12284 is a dual run capacitor rated at 35/7.5 microfarads (MFD) and 440 volts, designed for use in single-phase electric motor circuits found in residential and light commercial HVAC equipment. This round capacitor supports both the compressor and the condenser fan motor simultaneously, providing the phase shift needed for startup and continuous run operation. Its compact round housing fits standard capacitor brackets, making it a straightforward field replacement. Licensed HVAC technicians typically install this capacitor during seasonal tune-ups, no-cool service calls, or compressor and fan motor replacements.

This dual run capacitor is suited for split-system air conditioners and heat pumps where a single capacitor serves both the compressor and the outdoor fan motor. The 440-volt rating makes it compatible with both 208-volt and 240-volt single-phase applications, giving technicians flexibility across a range of residential and light commercial condensing units. Its round form factor is one of the most common configurations in the field, easing replacement in tight electrical compartments.

Key Features

• Dual-section design supports compressor and condenser fan motor from a single capacitor
• 35/7.5 MFD capacitance rating for split-system HVAC applications
• 440-volt rating suitable for 208-volt and 240-volt single-phase systems
• Round housing fits standard capacitor mounting brackets
• Compact footprint: 2.5 inches diameter by 4.375 inches tall

Compatibility

Designed as an OEM-style replacement dual run capacitor for residential and light commercial single-phase air conditioning and heat pump condensing units requiring a 35/7.5 MFD, 440-volt round capacitor.

Installation Notes

Installation should be performed by a licensed HVAC technician. Before servicing the capacitor, disconnect and lock out power to the condensing unit at the disconnect box and verify that the capacitor has been fully discharged before handling terminals, as capacitors can store a lethal charge even after power is removed. Confirm that the replacement MFD ratings and voltage rating meet or exceed the original equipment specifications before installing. Follow all applicable local electrical codes and the equipment manufacturer's wiring diagram when reconnecting terminals.
