Rcd p291-3004r Run Capacitor 30 Mfd 370/440V

Product Description

The RCD p291-3004r is a single-section oval run capacitor rated at 30 microfarads (MFD) and 370/440 volts AC for use in residential and light commercial HVAC systems. Run capacitors maintain the phase shift needed to keep PSC motors running smoothly after startup, correcting power factor and stabilizing current draw across the motor winding. This unit is constructed with a polypropylene film dielectric inside an aluminum case and carries a tolerance of plus or minus 6 percent. It operates across a frequency range of 50/60 Hz and is rated for temperatures from -29 to 68 degrees C. Licensed HVAC technicians install this part during compressor, condenser fan motor, or blower motor service calls.

The p291-3004r fits single-capacitor motor circuits in split-system air conditioners, heat pumps, and fan coil applications where a 30 MFD oval run capacitor at 370/440 volts AC is required. Its oval form factor suits enclosures designed for oval-body capacitors. Technicians typically source this part as a direct replacement when capacitance has drifted beyond tolerance or the existing capacitor shows physical signs of failure such as bulging or leaking.

Key Features

• 30 MFD rated capacitance with a tight plus or minus 6 percent tolerance for consistent motor performance
• Dual-rated voltage at 370/440 volts AC for compatibility across common residential and light commercial HVAC circuits
• Polypropylene film dielectric construction for stable electrical characteristics over service life
• Aluminum case in an oval form factor for straightforward drop-in replacement in standard capacitor brackets
• Wide operating temperature range of -29 to 68 degrees C suitable for outdoor condenser unit environments
• Single-section design for PSC motor run circuits — compressor, condenser fan, or blower

Compatibility

Designed as an OEM-style replacement run capacitor for single-section 30 MFD 370/440V oval capacitor applications in residential and light commercial HVAC equipment.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect and lock out all electrical power to the unit before opening the control or capacitor compartment. Capacitors store a charge even after power is removed — discharge the existing capacitor safely using an approved discharge tool before handling terminals or wiring. Verify replacement capacitance and voltage ratings match the motor nameplate and equipment wiring diagram before energizing the system.
