Rcd p291-3004 Run Capacitor 30 Mfd 440V Oval Single

Product Description

The RCD p291-3004 is a single oval run capacitor rated at 30 microfarads (MFD) and 440 volts AC, designed for use in HVAC equipment. Run capacitors provide continuous phase-shifted current to motor windings, maintaining efficient motor operation during normal system runtime. This unit is constructed with a metallized polypropylene dielectric, which offers stable capacitance across a wide operating temperature range of -40 to 70 degrees C. It is sized for replacement use in residential and light commercial air conditioning and heat pump systems and is typically installed by licensed HVAC technicians during routine capacitor replacement or motor service calls.

This capacitor is suited for single-capacitor applications where the compressor or condenser fan motor requires a dedicated run capacitor rather than a dual-rated unit. The oval form factor is common in Carrier and compatible HVAC equipment. It operates at 60 Hz and carries a capacitance tolerance of plus or minus 6 percent, keeping motor performance within acceptable design parameters under normal load conditions.

Key Features

• 30 MFD capacitance with a tight plus or minus 6 percent tolerance for consistent motor performance
• 440 volt AC rating provides headroom above standard 370-volt applications
• Metallized polypropylene construction for reliable dielectric stability
• Oval shape fits standard capacitor brackets and clips in residential and commercial air handlers and condensing units
• Single configuration isolates compressor or fan motor circuit without a shared dual capacitor
• Wide temperature rating from -40 to 70 degrees C supports operation across climate extremes

Compatibility

Listed as a genuine OEM replacement run capacitor for Carrier HVAC equipment. Consult the unit nameplate and wiring diagram to confirm capacitance and voltage requirements before installation.

Installation Notes

Run capacitor replacement is performed by licensed HVAC technicians. Always disconnect and lock out power to the unit before accessing the capacitor compartment. Capacitors store a charge even after power is removed — discharge the capacitor using an approved resistor tool before handling. Follow the original wiring diagram to ensure correct terminal connections, and verify that the replacement MFD rating and voltage rating match the equipment nameplate specifications.
