Rectorseal M12123 Dual Run Capacitor 80/7.5 Mfd 370V

Product Description

The RECTORSEAL M12123 is a dual run capacitor rated at 80/7.5 microfarads (MFD) and 370 volts, designed for use in residential and light commercial HVAC equipment. Dual run capacitors serve two motor circuits simultaneously, typically supporting both the compressor and the condenser fan motor from a single component. This oval-style capacitor is a direct replacement part installed by licensed HVAC technicians during routine service calls or component failure repairs. Its compact oval housing fits standard condenser unit mounting configurations and is suited for field replacement work.

This capacitor is commonly used in split-system air conditioners and heat pumps where the original equipment calls for an 80/7.5 MFD dual run capacitor at 370 volts. It is appropriate for residential condensing units and light commercial packaged equipment requiring this MFD and voltage rating. HVAC service technicians typically carry this capacitor as a standard replacement item for summer service season stock.

Key Features

• Dual run configuration supports compressor and condenser fan motor from one capacitor
• Rated at 80/7.5 MFD for split-circuit motor starting and running support
• 370-volt rating suitable for standard single-phase residential HVAC equipment
• Oval housing designed to fit common condenser unit capacitor brackets
• Compact dimensions simplify installation in tight electrical compartments

Compatibility

Designed as an OEM-style replacement dual run capacitor for residential and light commercial split-system air conditioners and heat pumps requiring an 80/7.5 MFD 370-volt oval capacitor.

Installation Notes

Dual run capacitors must be installed by a qualified HVAC technician. Always disconnect and lock out power to the condensing unit before opening the electrical access panel. Capacitors store a dangerous electrical charge even after power is removed — discharge the capacitor safely using an appropriate resistor or discharge tool before handling. Verify that the MFD ratings and voltage rating of the replacement capacitor match the equipment nameplate specifications before installation.
