Rcd p291-0554 Dual Run Capacitor 5+5 Mfd 440V Oval

Product Description

The RCD p291-0554 is a dual run capacitor designed to maintain continuous motor operation in residential and light-commercial HVAC systems. It supplies the sustained phase-shifted current that compressor and fan motors require to run efficiently once started. Rated at 5+5 MFD with a 440-volt AC rating and 50/60 Hz compatibility, this oval-shaped capacitor fits a wide range of split-system air conditioners and heat pumps. The aluminum construction and quick-connect terminals support straightforward field replacement. A tolerance of plus or minus 3 percent keeps capacitance within the tight range that motor performance depends on. Licensed HVAC technicians are the primary installers of this component.

This capacitor is suited for residential and light-commercial split-system installations where a single dual-rated capacitor serves both the compressor and condenser fan motor. It is commonly found in outdoor condensing units that accept an oval-style capacitor with quick-connect terminals. The 440-volt rating accommodates both 370-volt and 440-volt systems, making it a practical field replacement across a broad range of equipment. Install scenarios typically involve like-for-like substitution when a failed capacitor causes hard-start conditions, motor humming, or failure to run.

Key Features

• Dual-section run capacitor — one unit serves both compressor and condenser fan motor
• 5+5 MFD capacitance with plus or minus 3 percent tolerance for precise motor support
• 440-volt AC rating compatible with 370-volt and 440-volt systems
• 50/60 Hz rated for standard North American HVAC applications
• Quick-connect terminals for fast, tool-minimal field installation
• Oval form factor with aluminum construction suited to typical condensing unit capacitor brackets
• Temperature rated from -40 to 70 degrees C for outdoor service environments

Compatibility

Designed as an OEM-style replacement dual run capacitor for residential and light-commercial HVAC condensing units requiring a 5+5 MFD, 370-volt or 440-volt oval capacitor with quick-connect terminals.

Installation Notes

Installation should be performed by a licensed HVAC technician following local codes and manufacturer guidelines. Disconnect and lock out all power to the condensing unit before opening the capacitor access panel, and verify zero voltage across capacitor terminals with a multimeter before handling, as run capacitors retain a charge after power is removed. Match capacitance and voltage ratings exactly to the equipment nameplate before installing the replacement. Discharge the old capacitor through a resistor before disposal in accordance with local regulations.
