Rectorseal m12782 Dual Run Capacitor 440V 30/7.5 Mfd

Product Description

The RECTORSEAL m12782 is a dual section round run capacitor rated at 440 volts and 30/7.5 microfarads (MFD). Dual section run capacitors store and release electrical energy to start and maintain the operation of two motor windings simultaneously — typically the compressor and the fan motor in a split-system or packaged HVAC unit. By making various parallel connection combinations, this capacitor can also be configured to achieve additional MFD ratings beyond the standard 30/7.5 labeling. HVAC technicians install this type of component during routine capacitor replacement or as part of a compressor or fan motor swap.

This capacitor is suited for residential and light commercial HVAC applications where a single round dual-section capacitor serves both the compressor and condenser fan motor. Its 440-volt rating accommodates standard single-phase motor circuits commonly found in central air conditioning systems and heat pumps. The dual-section design reduces the number of capacitors needed in a single cabinet, simplifying the electrical compartment and easing future service access.

Key Features

• Dual section design serves two motor loads from one capacitor housing
• Rated at 440 volts for compatibility with standard single-phase HVAC motor circuits
• 30/7.5 MFD rating supports both compressor and condenser fan motor windings
• Round form factor fits standard capacitor brackets and mounting straps
• Parallel connection flexibility allows additional MFD combinations for varied applications

Compatibility

Designed as an OEM-style replacement dual run capacitor for residential and light commercial air conditioning and heat pump systems requiring a 440-volt, 30/7.5 MFD round dual section capacitor.

Installation Notes

Installation should be performed by a licensed HVAC technician. Always disconnect and lock out power to the unit before handling capacitors, and discharge the capacitor fully using an insulated discharge tool before removing terminals — stored charge can be present even after power is off. Verify that the replacement MFD rating and voltage rating match the original nameplate specifications before energizing the system. Follow all applicable NEC requirements for low-voltage motor circuit components during installation.
