Rheem-Ruud 43-25135-17 Capacitor

The Rheem-Ruud 43-25135-17 Dual Run Capacitor is a high-grade 35/3 microfarad (MFD) component designed for 370 VAC circuits, serving as a critical replacement part for condensing units and package systems. Professionals recognize its oval dual run configuration as a standard for reliable compressor and fan motor ignition and operation. As an OEM HVAC replacement part, this ProTech dual capacitor is engineered to meet UL 810 safety standards with a 5,000 AFC (Available Fault Current) rating, ensuring the safety of the electrical assembly during unexpected surges. The Rheem-Ruud 43-25135-17 features 1/4 inch quick-connect terminals for a secure interface in tight control boxes. Measuring approximately 3.94 inches in maximum height, this 35/3/370 dual oval capacitor provides the stable capacitance required to maintain peak efficiency in HVAC motors without the risks associated with non-certified generic alternatives.

Key Benefits:

• OEM Precision: Specifically calibrated for Rheem, Ruud, and WeatherKing equipment to ensure factory-spec performance.
• High Dielectric Strength: Rated for 370 Vac to handle the voltage demands of standard residential and light commercial units.
• Safety Compliance: UL 810 certified and tested to 5,000 AFC to protect your equipment from electrical failure.
• Compact Oval Form: The oval dual run footprint allows for easy installation in service panels where space is a constraint.
• Dual-Function Reliability: Simultaneously manages the 35 MFD compressor load and 3 MFD fan motor load from a single housing.

Common Questions:

Can I use a round capacitor to replace this oval model?
Yes, as long as the 35/3 uF rating and 370V (or higher) voltage match, you can use a round capacitor if the mounting bracket in the unit accommodates the shape change.

What happens if the capacitance drops below the 35/3 MFD rating?
Lowered capacitance leads to increased heat in the motor windings, higher amperage draw, and eventual failure of the compressor or fan motor.

Is the 43-25135-17 compatible with 440V systems?
No, this component is rated for 370 VAC. While a 440V capacitor can replace a 370V unit, a 370V capacitor cannot be used in a 440V application.
