Trane CPT0444 Run Capacitor

The Trane CPT0444 is a professional-grade 25 Microfarad 440Vac Oval Run Capacitor designed for continuous motor operation in residential and commercial HVAC systems. This OEM Trane capacitor is the engineered direct replacement for the legacy CTP0444, ensuring seamless mechanical and electrical compatibility. Constructed with a durable aluminum casing and a compact oval profile, it facilitates straightforward installation in tight control boxes where space is at a premium. As a 25 MFD 440V run capacitor, it is rated for both 370V and 440V applications, providing technicians with a versatile field solution for maintaining optimal motor torque and efficiency. This non-PCB, fluid-filled component is vital for stabilizing the electrical phase shift in compressor and fan motor circuits, reducing amp draw and thermal stress. For contractors servicing Trane, American Standard, or cross-referenced equipment, the Trane CPT0444 offers the reliability required for high-duty cycle performance in demanding environments.

• Direct OEM Match: Precision-engineered as the official replacement for part number CTP0444, eliminating mounting and wiring discrepancies.
• Dual Voltage Compatibility: Rated at 440Vac, this unit safely replaces 370Vac capacitors, providing increased dielectric strength and field reliability.
• Optimized Form Factor: The traditional oval can design fits standard mounting brackets in a wide range of air handlers and condensing units.
• Electrical Stability: Maintains a consistent 25 uF capacitance to protect motor windings from overheating and premature failure.

Can the CPT0444 be used if my original capacitor is 370V?
Yes, a 440V capacitor is a superior technical upgrade for a 370V application as it can handle higher voltage surges while maintaining the required 25 MFD capacitance.

What is the difference between CPT0444 and CTP0444?
The CPT0444 is the current production part number used by Trane to replace the older CTP0444 designation. They are functionally and physically identical.

Will this capacitor work for both fan motors and compressors?
As long as the equipment specifications call for a single-value 25 MFD run capacitor at 440V or lower, it is suitable for either application.
