Carrier P291-2504 Run Capacitor

The Carrier P291-2504 is a professional-grade 25 MFD 440V run capacitor designed for high-performance motor applications in commercial and residential HVAC systems. This oval run capacitor serves as the direct OEM replacement for the legacy P291-2503 model, engineered to handle the electrical demands of permanent split capacitor (PSC) motors. Rated for 440 VAC and 50/60 Hz operation, it provides the necessary phase shift to optimize motor torque and operational efficiency, reducing amperage draw and extending the service life of compressors and blower motors.

Constructed with high-grade metallized polypropylene film, the Carrier P291-2504 capacitor features a pressure-sensitive interrupter (10,000 AFC) for safety and is housed in a hermetically sealed aluminum case to resist environmental contaminants. This HVAC motor run capacitor is rated for continuous duty with a wide operating temperature range from -40°C to 70°C. It utilizes standard 1/4-inch quick-connect terminals for seamless field integration. As a Totaline capacitor, it meets rigorous reliability standards, ensuring compatibility across a broad range of Carrier, Bryant, and Payne equipment.

• Precise 25 Microfarad Rating: Maintains proper electrical phase shift for optimized compressor starts and motor efficiency.
• Dual Voltage Compatibility: Rated for 440V but is backwards compatible for 370V applications where space permits.
• Robust Safety Features: Built-in 10,000 AFC pressure-sensitive interrupter prevents casing rupture during internal failure.
• OEM Standards: Explicitly designed as a drop-in replacement for P291-2503, eliminating mounting or wiring modifications.
• Durable Construction: Non-PCB oil-filled design ensures superior heat dissipation and environmental compliance.

• Can I use this 440V capacitor to replace a 370V 25 MFD capacitor? Yes, you can always upgrade to a higher voltage rating as long as the capacitance (MFD) matches and the oval physical dimensions fit your mounting bracket.
• Is the P291-2504 compatible with non-Carrier equipment? While designed for Carrier family units, this is a universal-style oval run capacitor that works with any motor requiring a 25 MFD 440V/370V rating.
• Why does the capacitor I received have a different brand name? Carrier sources capacitors from various high-quality manufacturers; the technical specifications and part number validation remain the primary indicators of compatibility.
