Rectorseal M12281 Dual Run Capacitor 30/5 Mfd 440V

Product Description

The RECTORSEAL M12281 is a dual run capacitor rated at 30/5 MFD and 440 volts, designed for use in residential and light commercial HVAC systems. Dual run capacitors serve two motor circuits simultaneously, supporting both the compressor and the condenser fan motor from a single component. The round form factor fits standard capacitor brackets and disconnect configurations. HVAC technicians install this part during routine maintenance, seasonal startups, and component failure calls when the original capacitor tests out of tolerance or shows physical signs of failure.

This capacitor is appropriate for split-system air conditioners and heat pumps where the compressor and condenser fan motor share a single capacitor assembly. The 440-volt rating provides a suitable safety margin for systems running on standard 208/230-volt single-phase power. Its round housing fits common run capacitor mounting hardware found in a wide range of condensing units.

Key Features

• Dual run capacitor supports compressor and condenser fan motor from one unit
• 30/5 MFD dual-section rating for two-motor applications
• 440-volt rating suitable for 208/230-volt single-phase HVAC systems
• Round form factor fits standard capacitor mounting brackets
• Compact dimensions: 2.0 x 2.0 x 4.375 inches

Compatibility

Designed as an OEM-style replacement dual run capacitor for residential and light commercial split-system air conditioners and heat pumps requiring a 30/5 MFD, 440-volt round capacitor.

Installation Notes

Dual run capacitors must be installed by a licensed HVAC technician. Always disconnect and lock out power to the condensing unit before servicing. Capacitors store a charge and must be safely discharged before handling, even after power is removed. Verify the MFD ratings and voltage rating of the replacement capacitor match the original unit nameplate specifications before installation.
