Rcd p291-3574rs Dual Run Capacitor 35/7.5 Mfd 440V

Product Description

The RCD p291-3574rs is a dual run capacitor rated at 35/7.5 microfarads (MFD) and 440 volts AC, designed for continuous-duty operation in residential and light commercial HVAC systems. Run capacitors maintain the phase shift needed to keep compressor and fan motors running efficiently after startup. This round aluminum capacitor operates across a wide temperature range and carries quick-connect terminals for straightforward field replacement. HVAC technicians install this part during routine maintenance or when a failed capacitor is identified as the cause of compressor or condenser fan motor issues.

This capacitor is suited for split-system air conditioners and heat pumps where a single dual-rated capacitor serves both the compressor and the outdoor fan motor. Compatible models listed in the manufacturer data include 38BRB036 310, 598ANX036000ABAA, and 698ANX036000ACAA. It is an OEM-replacement-style part intended for outdoor condensing unit applications in systems that require a 35+7.5 MFD dual configuration at 440 volts.

Key Features

• Dual capacitance rating of 35+7.5 MFD serves both compressor and fan motor circuits in one unit
• 440 volt AC rating provides compatibility with standard single-phase residential condensing units
• Quick-connect terminals allow fast, tool-light field swaps
• Round aluminum housing resists corrosion in outdoor installation environments
• Wide temperature rating of -40 to 70 degrees C supports operation in extreme climate conditions
• Plus or minus 6% capacitance tolerance meets OEM-grade accuracy requirements

Compatibility

Compatible models provided in product data include 38BRB036 310, 598ANX036000ABAA, and 698ANX036000ACAA. Verify system voltage, MFD ratings, and terminal configuration before installation.

Installation Notes

Capacitor replacement is performed by licensed HVAC technicians. Disconnect and lock out all power to the condensing unit before opening the electrical compartment. Capacitors store a charge even after power is removed — discharge the capacitor safely using an appropriate resistive discharge tool before handling. Verify that the replacement MFD values and voltage rating match the original unit nameplate specifications exactly before connecting terminals.
