Rheem-Ruud 43-25133-34 Dual Capacitor

The Rheem-Ruud 43-25133-34 is a professional-grade 80/10 MFD 370V dual run capacitor designed for demanding HVACR applications requiring high capacitance for both the compressor and condenser fan motor. Built to the ProteCH OEM standard, this round dual run capacitor features a robust aluminum electrolytic construction to handle high internal pressures and thermal stress. It is rated for 370 VAC operation, providing the necessary phase shift for efficient motor startup and operation in outdoor condensing units. The 80 microfarad and 10 microfarad ratings are critical for maintaining the correct torque and RPM, preventing premature motor winding failure. Technicians should note the physical dimensions and terminal configuration to ensure a secure fit within the control box. This HVAC replacement capacitor is engineered for a temperature range of -40°C to +70°C, ensuring reliable performance during peak summer loads when system amperage draw is at its highest.

• Dual-Action Performance: Combined 80/10 uF rating services both the compressor and fan motor from a single component.
• OEM Compatibility: Precision-engineered for Rheem and Ruud equipment, ensuring correct capacitance tolerances.
• High Thermal Stability: Designed to dissipate heat effectively during continuous duty cycles in high-ambient environments.
• Internal Pressure Interrupter: Integrated safety mechanism disconnects the capacitor in the event of an internal fault.
• Reliable Phase Shift: Optimizes motor efficiency and reduces amperage draw, extending the service life of expensive system components.

Can I use a 440V capacitor to replace this 370V 43-25133-34 model?
Yes, a 440VAC capacitor can be used as a substitute for a 370VAC unit, as the voltage rating indicates the maximum threshold the dielectric can handle. However, the capacitance must remain exactly 80/10 MFD.

What are the symptoms of a failing 80/10 dual run capacitor?
Common indicators include a humming compressor that fails to start, a condenser fan spinning slowly or not at all, and visible bulging or leaking of the capacitor casing.

Does the polarity of the terminals matter during installation?
While the capacitor itself is non-polarized, the wiring configuration is critical. Always connect the common wire to 'C', the compressor lead to 'Herm', and the fan motor lead to 'Fan' to ensure proper circuit operation.
