Trane CPT0072 Capacitor

The Trane CPT0072 is a high-performance 5 Microfarad 370Vac Oval Run Capacitor specifically engineered for HVACR condenser fan and blower motor applications. Built to rigorous OEM technical specifications, this single-section run capacitor provides the steady phase shift required by Permanent Split Capacitor (PSC) motors found in Trane and American Standard residential units. Rated for 370 Volts Alternating Current (VAC), this component is designed for continuous operation at 50/60 Hz, ensuring consistent torque and thermal management. The oval can design and dual quick-connect terminals allow for a drop-in replacement in tight electrical service cabinets. Technicians often source this part by the C112002P01 or CPT00072 part numbers. Using a high-grade metallized film dielectric and a non-PCB oil-filled housing, the CPT0072 maintains a stable 5 MFD capacitance tolerance within +/- 6% across standard operating temperature ranges. Ensuring your motors have the correct microfarad rating is critical for preventing winding burnout and maintaining system SEER ratings.

• Precision Capacitance: Rated at 5 MFD to ensure correct motor torque and electrical efficiency in blower and fan motors.
• OEM Fitment: Genuine Trane replacement part, ensuring compatibility with Trane/American Standard equipment mounting brackets.
• Industrial Housing: Features a moisture-resistant, oval aluminum casing with a built-in pressure-sensitive interrupter for safe internal disconnection.
• Wide Replacement Compatibility: Directly replaces part numbers CPT0072, CPT00072, CPT72, and CPT00748.

• Can I use this 370V capacitor in place of a 440V version? No. While you can often use a higher voltage capacitor (like a 440V) to replace a 370V unit, you should never down-rate a 440V requirement with a 370V capacitor like the CPT0072.
• What happens if the MFD rating is off? Running a motor with a capacitor that is ±10% outside of its 5 MFD specification can lead to overheating, increased amp draw, and eventual motor failure.
• Does the "oval" shape matter for electrical performance? The shape is purely for physical fitment. If your original mount was for a round capacitor, you will need to modify the mounting strap to secure this oval unit.
