Rcd p291-5504 Run Capacitor 55 Mfd 440V Oval Single

Product Description

The RCD p291-5504 is a single-section oval run capacitor rated at 55 microfarads (MFD) and 440 volts AC, designed to stabilize motor current and maintain efficient operation in HVAC systems. Run capacitors provide a continuous phase-shifted current to the run winding of single-phase motors, smoothing torque delivery and reducing heat buildup during sustained operation. The polypropylene film dielectric and aluminum case construction support reliable performance across a wide temperature range of -29 to 68 degrees C. Licensed HVAC technicians install this capacitor as a direct OEM-replacement component in residential and light-commercial cooling equipment.

This capacitor is suited for single-phase PSC motor applications found in packaged rooftop and split-system air conditioning units. The oval form factor and quick-connect terminals match the footprint and wiring interface of the original factory part, allowing straightforward drop-in replacement during a service call. Compatible models listed by the manufacturer include Carrier units 50QJ 006 660, 50QJ 006 160, and 50QJ 006 560.

Key Features

• 55 MFD capacitance with a tight plus-or-minus 6 percent tolerance for consistent motor performance
• 440V AC rating accommodates both 370V and 440V motor circuits
• Dual-frequency rated at 50/60 Hz for broad application compatibility
• Oval aluminum case with quick-connect terminals for fast, tool-minimal installation
• Wide operating temperature range of -29 to 68 degrees C suits outdoor condensing unit environments
• Single-section design simplifies replacement identification and stocking

Compatibility

Confirmed compatible with Carrier packaged units 50QJ 006 660, 50QJ 006 160, and 50QJ 006 560 as stated by the manufacturer. Designed as an OEM-style replacement for single-phase PSC motor run capacitor applications in residential and light-commercial HVAC equipment.

Installation Notes

A licensed HVAC technician should perform capacitor replacement. Disconnect and lock out all power to the unit before opening the electrical compartment. Capacitors retain a dangerous charge after power is removed and must be safely discharged through an appropriate resistive load before handling. Verify the replacement MFD rating and voltage rating match the motor nameplate specifications before installing.
