Rectorseal M12063 Dual Run Capacitor 20/5 Mfd 370V

Product Description

The RECTORSEAL M12063 is a dual run capacitor rated at 20/5 MFD and 370 volts, designed to support both the compressor and the condenser fan motor in a split-system or packaged HVAC unit. Run capacitors maintain the phase shift needed to keep motors running efficiently after startup. This oval-style capacitor delivers stable capacitance across both circuits in a compact form factor measuring approximately 1.806 inches wide, 2.806 inches long, and 3.125 inches tall. It is installed by licensed HVAC technicians during routine maintenance or component replacement.

This capacitor is suited for residential and light commercial air conditioning and heat pump systems where a single oval dual run capacitor serves both the compressor and fan motor circuits. The 20/5 MFD dual rating and 370-volt specification make it a common replacement in split-system condensing units. Its oval housing fits standard capacitor mounting brackets found in most outdoor condensing units.

Key Features

• Dual run capacitor supports compressor (20 MFD) and condenser fan motor (5 MFD) from a single unit
• Rated at 370 volts for compatibility with standard single-phase residential HVAC systems
• Oval form factor fits typical condensing unit capacitor brackets
• Compact dimensions: 1.806 inches wide by 2.806 inches long by 3.125 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 20/5 MFD 370-volt oval capacitor.

Installation Notes

Dual run capacitors are replaced by licensed HVAC technicians. Disconnect and lock out power to the condensing unit before servicing, and discharge the existing capacitor fully before handling — capacitors retain a lethal charge even after power is removed. Verify the replacement MFD ratings and voltage rating match the equipment nameplate before installation. Follow all applicable NEC and equipment manufacturer guidelines during service.
