Rcd p291-4054rs Dual Run Capacitor 40+5 Mfd 440V

Product Description

The RCD p291-4054rs is a dual run capacitor designed for residential and light commercial HVAC systems. It operates at 370/440 volts AC with a capacitance rating of 40+5 microfarads (MFD) and a frequency rating of 50/60 Hz. The round aluminum housing measures 5.75 inches in length and 2.5 inches in diameter. This capacitor provides the sustained electrical charge needed to keep both the compressor and condenser fan motor running at rated efficiency. Licensed HVAC technicians install this part as a direct OEM-style replacement during routine maintenance or when a failed capacitor is identified as the cause of a non-starting or hard-starting system.

The p291-4054rs is suited for split-system air conditioners and heat pumps where a single dual-run capacitor serves both the compressor and outdoor fan motor. Compatible units noted in supplier data include the 50VL C24 30, 50VG A60 30, and 50TM 005 300 series, among others. The quick-connect terminals simplify field installation and reduce service time on the call. This part is appropriate for residential rooftop package units and split condensing units requiring a 40+5 MFD dual configuration.

Key Features

• Dual-section run capacitor rated 40+5 MFD serves compressor and fan motor from a single component
• Rated for 370/440V AC operation, compatible with standard residential and light commercial supply voltages
• Round aluminum housing with quick-connect terminals for straightforward field replacement
• 50/60 Hz rated for use on standard North American power systems
• Tolerance of plus or minus 6 percent meets typical OEM specification requirements
• Temperature rating of -29 to 68 degrees C supports operation across a wide range of ambient conditions

Compatibility

Confirmed compatible units include the 50VL C24 30, 50VG A60 30, and 50TM 005 300 series. Consult the full fits-models list provided by the manufacturer for a complete compatibility reference before installation.

Installation Notes

Capacitor replacement is performed by a licensed HVAC technician. Disconnect and lock out all power to the unit before opening the electrical compartment, and discharge the existing capacitor fully before handling — stored charge can cause serious injury even after power is removed. Verify the replacement MFD rating and voltage rating match the original unit nameplate before connecting terminals. Follow applicable NEC requirements for low-voltage wiring and equipment access when servicing the outdoor condensing unit.
