Rcd p291-3074r Dual Run Capacitor 30/7.5 Mfd 440V

Product Description

The RCD p291-3074r is a dual-run capacitor designed to stabilize motor performance and maintain consistent operation in residential and light commercial HVAC systems. Rated at 30+7.5 microfarads (MFD) with a 440V AC working voltage, this round capacitor supports both the compressor and fan motor circuits simultaneously through a single component. Built with a polypropylene film dielectric and an aluminum case, it is engineered to hold capacitance within a tight plus-or-minus 3% tolerance across a wide operating temperature range of -40 to 70 degrees C. Licensed HVAC technicians install this part as a direct OEM-style replacement during routine service or capacitor failure diagnostics.

This capacitor is suited for split-system air conditioners, heat pumps, and packaged units where a single dual-run capacitor serves both the compressor and condenser fan motor. It is commonly replaced during warm-weather service calls when capacitor degradation causes hard-start conditions, reduced motor torque, or elevated amperage draw. The quick-connect terminals allow for straightforward wiring without special tooling, making swap-out efficient during field service. The 50/60 Hz rating covers standard North American and international grid frequencies.

Key Features

• Dual capacitance rating of 30+7.5 MFD serves compressor and fan motor circuits in one unit
• 440V AC working voltage provides compatibility with modern high-efficiency HVAC equipment
• Polypropylene film dielectric with aluminum case for thermal stability and long service life
• Tight plus-or-minus 3% capacitance tolerance supports consistent motor performance
• Quick-connect terminals for fast, tool-free wiring during field replacement
• Rated for 50/60 Hz operation across a -40 to 70 degrees C temperature range

Compatibility

Designed as an OEM-style replacement dual-run capacitor for residential and light commercial HVAC systems requiring a 30+7.5 MFD, 440V AC round capacitor with quick-connect terminals.

Installation Notes

Installation must be performed by a licensed HVAC technician. Disconnect and lock out all power to the unit before accessing the capacitor compartment, and use a capacitor discharge tool to safely bleed stored voltage before handling the old capacitor. Verify the replacement capacitance and voltage ratings match the equipment nameplate requirements before installing. Confirm all quick-connect terminals are fully seated and that the capacitor is secured in its mounting bracket before restoring power.
