Trane SFCAP25440R Run Capacitor

The Trane SFCAP25440R Run Capacitor is a 25 MFD 440V Round Run Capacitor engineered for high-performance service in residential and commercial condensing units. As the verified OEM replacement for CPT0467, this motor run capacitor ensures electrical stability and peak efficiency for single-phase motors. Rated for 370V/440V environments, the Trane SFCAP25440R features a robust aluminum "round can" design that fits standard mounting brackets without modification. This HVAC part is essential for maintaining the correct phase shift required for compressor and fan motor operation, effectively reducing amperage draw and operational heat. Whether you are performing a seasonal tune-up or an emergency repair, utilizing a genuine Trane 25 microfarad capacitor eliminates the reliability risks associated with generic alternatives. Its non-PCB, oil-filled construction provides superior heat dissipation and dielectric strength, making it the preferred choice for veteran contractors dedicated to restoring system performance to factory specifications.

• Direct OEM Replacement: Designed specifically to replace the Trane CPT0467, ensuring perfect physical and electrical compatibility.
• Dual Voltage Rated: Operates efficiently at both 370 VAC and 440 VAC, providing versatility for various field applications.
• Standardized Fit: The round profile and 2.5-inch diameter allow for seamless installation in existing capacitor straps and enclosures.
• Industrial Grade Reliability: Built with high-tolerance internal components to sustain constant duty cycles in demanding HVACR environments.
• Quick-Connect Terminals: Features standard 1/4-inch terminals for fast and secure wiring connections during field service.

Is the SFCAP25440R compatible with systems currently using a 370V capacitor?
Yes. This 440V capacitor is a heavy-duty upgrade for 370V applications. While you cannot use a lower-rated capacitor in a higher-voltage circuit, a 440V unit like the SFCAP25440R provides increased dielectric strength and safety margin for 370V systems.

What are the signs that a 25 MFD capacitor needs replacement?
Technicians should look for physical bulging at the top of the canister, oil leakage, or "hard starting" where the motor hums but fails to rotate. Accurate diagnosis requires testing with a multimeter to ensure the microfarad reading remains within the +/-5% tolerance range.

Can I use this round capacitor to replace an oval-shaped CPT0467?
The SFCAP25440R is the official technical successor to older 25 MFD versions. While the electrical specifications are identical, if your original part was oval, you may need a standard round mounting strap to secure this unit properly within the control box.
