Carrier P291-8054R Run Capacitor

The Carrier P291-8054R is a high-performance 80/5 MFD 440V round run capacitor engineered for demanding HVACR applications. As an 80+5 microfarad dual-run component, it provides the necessary phase shift for both the compressor and the condenser fan motor, ensuring efficient startup and sustained operation. This model serves as the direct OEM replacement for P291-8053RS, maintaining the exact electrical specifications required by Carrier, Bryant, and Payne equipment. Constructed with high-grade metallized polypropylene film and housed in a rugged aluminum casing, it is rated for 370/440VAC and tested to 60,000 service hours. The integrated pressure-sensitive interrupter (PSI) enhances safety by disconnecting the capacitor in the event of internal failure, preventing casing rupture. This HVAC dual run capacitor operates reliably within a temperature range of -40°C to 70°C, making it a standard choice for technicians performing AC capacitor replacement on high-amperage systems.

• Direct Compatibility: Exact electrical match for the discontinued P291-8053RS, ensuring no modifications to the mounting bracket or wiring.
• Dual-Rated Voltage: Designed for 440V applications but fully backward compatible with 370V systems for increased field versatility.
• Industrial-Grade Reliability: 10,000 AFC (Available Fault Current) protection and 100% electrical testing to meet stringent OEM performance standards.
• Broad Operating Range: Built to withstand extreme ambient temperatures in outdoor condenser units without capacitance drift.

• Can I use this to replace a 370V capacitor? Yes, a 440V rated capacitor can always be used to replace a 370V model of the same MFD rating, as it offers a higher dielectric strength.
• How do I identify the terminals? The terminals are clearly marked: 'Herm' for the compressor, 'Fan' for the condenser fan, and 'C' for the common line.
• What happens if the capacitance drops? If the 80/5 MFD rating deviates by more than 5-10%, motor torque decreases, leading to overheating or "hard starting" of the compressor.
