Carrier P291-0774 Capacitor

The Carrier P291-0774 Capacitor is a high-performance 7.5/7.5 MFD 440V oval capacitor engineered for demanding HVACR applications. As a direct OEM replacement for the obsolete P291-0773 and HC93CA011, this dual-run component is designed to handle the continuous duty cycles of both the compressor and the condenser fan motor. Built to satisfy EIA-456 standards, it features an oval-shaped aluminum casing that fits into the tight service panels often found in Carrier, Bryant, and Payne condenser units.

This capacitor is rated for 370V/440V applications, providing the versatility needed for field service across various voltage requirements. With a tolerance of +/- 5% and a wide operating temperature range of -40°C to 70°C, it ensures stable capacitance under extreme thermal loads. Technicians should note the dual-run configuration and standard 1/4-inch male quick-connect terminals, which facilitate rapid installation. This genuine Totaline P291-0774 ensures your system maintains the correct phase shift and torque efficiency mandated by factory specifications.

• Universal Compatibility: Direct physical and electrical drop-in for P291-0773, HC93CA011, and HCKS075D075V440102Z.
• Dual-Rated Voltage: Operates efficiently at both 370 VAC and 440 VAC, reducing the need for multiple skus on the truck.
• Extreme Durability: Constructed with metalized polypropylene film and a safety pressure interrupter to prevent housing rupture.
• Precise Performance: Maintains exact 7.5+7.5 microfarad ratings to prevent motor overheating and premature failure.

Can I use an oval capacitor to replace a round one?
Yes, provided the 7.5/7.5 MFD and 440V ratings match and the oval footprint fits securely within the mounting strap or capacitor boot.

What is the difference between P291-0774 and P291-0773?
The P291-0774 is the current OEM successor. It offers improved dielectric strength and is fully backward compatible with the older 370V P291-0773 models.

How do I identify a failing dual-run capacitor in the field?
Look for physical bulging of the aluminum can, oil leaks, or a significant drop in microfarad readings during a bench test with a multimeter.
