Rectorseal M12147 Oval Run Capacitor 30/10 Mfd 370V

Product Description

The RECTORSEAL M12147 is a dual-run capacitor rated at 30/10 microfarads (MFD) and 370 volts, designed for use in residential and light commercial HVAC systems. Dual-run capacitors serve two motor loads simultaneously, typically supporting both the compressor and the condenser fan motor from a single component. This oval-style capacitor provides stable capacitance to maintain proper motor start and run performance. Licensed HVAC technicians install this component during routine maintenance, system diagnostics, or capacitor replacement calls.

This capacitor fits into split-system air conditioners and heat pumps that require a single dual-run capacitor for the compressor and condenser fan motor. Its oval form factor suits equipment with capacitor brackets sized for oval-style units. The 370-volt rating makes it appropriate for standard single-phase residential and light commercial condensing units. Always verify the MFD ratings and voltage rating match the existing capacitor and equipment nameplate before installation.

Key Features

• Dual-run design supports compressor and condenser fan motor from one capacitor
• 30/10 MFD dual capacitance rating for split-system HVAC applications
• 370-volt rating suitable for standard single-phase residential condensing units
• Oval form factor fits common capacitor mounting brackets in condensing units
• Compact dimensions allow fitment in tight equipment compartments

Compatibility

Designed as an OEM-style replacement dual-run capacitor for single-phase residential and light commercial air conditioners and heat pumps requiring a 30/10 MFD, 370-volt oval capacitor.

Installation Notes

Installation must be performed by a licensed HVAC technician. Disconnect and lock out all power to the condensing unit before handling any capacitor. Capacitors store a lethal electrical charge even after power is removed — always discharge the capacitor using an appropriate discharge tool before touching terminals. Verify the replacement MFD ratings and voltage rating match the original unit nameplate specifications before connecting leads.
