Trane SFCAP10440 Run Capacitor

The Trane SFCAP10440 Run Capacitor is a high-performance 10 MFD 440V run capacitor engineered for demanding HVACR applications. As a direct OEM replacement capacitor, this unit serves as the updated technical equivalent for legacy part numbers CPT0088, CAP0088, and CPT00088. Designed for the precise phase-shift requirements of single-phase motors, it ensures stable torque and optimal efficiency for fan motors and compressors in residential and commercial equipment. The 370/440V dual voltage rating provides superior dielectric strength, allowing it to safely replace 370V capacitors while offering enhanced thermal stability under high-load conditions. Its oval oil-filled capacitor housing fits standard mounting brackets, making it a reliable choice for field repairs where exact tolerances are required to maintain motor winding integrity and cooling performance.

Technical Benefits:

• Direct OEM Compatibility: Specifically engineered for Trane and American Standard units to ensure correct microfarad tolerance and electrical performance.
• Superior Voltage Protection: Rated for up to 440VAC, providing a robust overhead for voltage fluctuations compared to standard 370V components.
• High-Grade Construction: Built to meet strict HVAC capacitor specifications, utilizing high-quality internal materials to prevent premature ESR (Equivalent Series Resistance) buildup.
• Seamless Retrofit: Replaces outdated Trane CPT00088 and CPT0088 models without requiring mounting modifications.

Common Questions:

Can I use an oval capacitor to replace a round one?
Electrically, if the 10 MFD and voltage ratings match, the unit will function correctly. However, for physical installation, ensure your mounting strap is compatible with the oval run capacitor profile to maintain a secure fit.

Is this capacitor suitable for both 370V and 440V systems?
Yes. This 440 volt capacitor is rated for higher electrical stress, making it an ideal upgrade for 370V systems, as it can handle the lower voltage while providing increased durability.

What are the symptoms of a failing Trane SFCAP10440?
Look for a bulging top casing, oil leaks, or a motor that hums but fails to start. Testing with a multimeter should show a reading within +/- 5% or 6% of the 10 MFD rating depending on the specific tolerance level.
