Carrier HD680018 Motor

The Carrier HD680018 Motor is a high-performance 3 HP 3-phase motor engineered for demanding commercial and industrial HVACR applications. As a genuine OEM replacement motor, it is the direct factory-authorized upgrade for the discontinued HD58DL851 and P261-7802 models. This 230/460V HVAC motor features a dual-voltage configuration, operating efficiently at 208-230/460 VAC to provide maximum field flexibility for belt drive blower systems in rooftop units and air handlers. With a standard 1750 RPM operating speed and 60Hz frequency, it ensures consistent airflow and system static pressure management. Built with a rolled steel frame and a rugged aluminum flange, this heavy-duty motor is designed to withstand the high-torque demands and harsh environments typical of large-scale Carrier blower motor replacement projects. Contractors can rely on this 3-phase 3HP motor for an exact drop-in fit, maintaining all agency safety listings and original equipment specifications.

• Direct OEM Compatibility: Engineered as the exact replacement for HD58DL851 to ensure seamless mechanical and electrical integration without modifications.
• Industrial-Grade Build: Utilizes a rolled steel frame and aluminum flange for superior heat dissipation and structural integrity in commercial HVAC maintenance.
• High-Efficiency Performance: The 3-phase 230/460V design minimizes amperage draw (8.9A at 230V / 4.5A at 460V), reducing operational costs and electrical stress.
• Versatile Application: Optimized for belt drive blower assemblies, providing the necessary torque for large-diameter fan wheels and high-static air distribution.

What is the frame size and shaft dimension for the HD680018?
This Carrier 3HP motor typically follows NEMA standard dimensions for 3-horsepower industrial motors to facilitate a drop-in HVAC part replacement. Always verify your specific mounting bracket and pulley bore size before installation.

Can this motor be used in 208V 3-phase applications?
Yes, the Carrier HD680018 is rated for 208-230/460V, making it compatible with most commercial HVAC systems using 208V 3-phase power, though amperage draw will increase slightly to approximately 9.4A.

Is this a suitable replacement for a single-phase motor?
No, this is a dedicated 3-phase HVAC motor. It requires a 3-phase power supply and is not compatible with single-phase residential electrical configurations.
