Rheem-Ruud 43-25133-02 Run Capacitor

Engineered for professional-grade reliability, the Rheem-Ruud 43-25133-02 Run Capacitor is a high-performance 30/3 MFD 370V dual run capacitor designed to stabilize voltage and optimize the electrical efficiency of Rheem AC units and Ruud heat pumps. This OEM HVAC capacitor features a dual-circuit metallurgy that supports both the compressor (30 microfarads) and the condenser fan motor (3 microfarads), ensuring a consistent phase shift and reduced motor torque ripple during heavy-load cycles. Constructed with a seamless round run capacitor aluminum housing and high-grade metallized polypropylene film, it is rated for a 370VAC operating threshold, providing essential protection against voltage spikes and thermal degradation in extreme ambient temperatures.

For service technicians, this dual round motor run capacitor offers direct-fit compatibility, eliminating the need for mounting bracket modifications in Rheem and Ruud equipment. It incorporates a patented Pressure Sensitive Interrupter (PSI) and is UL 810 certified for safety, tested to 10,000 AFC to prevent circuit failures. Whether you are addressing a compressor not starting or replacing a swollen HVAC capacitor, the 43-25133-02 delivers the precise capacitance required for Protech motor support and long-term system stability.

Common Questions

Can I use a 440V capacitor to replace this 370V model?
Yes, you can always upgrade to a higher voltage rating (e.g., 440VAC), as it provides additional dielectric strength. However, never undersize the voltage rating below the 370V requirement of this unit.

How do I identify the terminals on this dual capacitor?
The terminals are labeled "C" for Common, "HERM" for the compressor, and "FAN" for the condenser fan motor. Always verify your wiring against the system schematic before energizing.

What are the physical dimensions for mounting?
This capacitor features a standard 2.12-inch diameter with a maximum height of 4.13 inches, fitting standard round mounting straps found in most Rheem condensing units.
