Century Motors 372A Motor

The Century Motors 372A is the direct engineering successor to the legacy 372 model, transitioning your equipment to a high-efficiency Permanent Split Capacitor (PSC) motor design. This 1/25 HP OEM replacement motor is purpose-built for light-duty HVAC applications, operating at a reliable 1060 RPM with 2-speed versatility. Housed in a 42 frame with a compact 5-inch diameter, this unit fits precisely into tight furnace and air handler enclosures. The open air over (OAO) construction ensures maximum thermal dissipation by utilizing the system's airflow to cool the internal windings, supporting continuous duty cycles under standard 115V single-phase power.

For contractors, the 372A motor simplifies field installation with its double shaft configuration (1/2" diameter with flats) and resilient ring mounting. This setup effectively dampens operational harmonics, reducing noise and vibration across the ductwork. Equipped with sleeve bearings and automatic thermal protection, this motor is designed to withstand the high-temperature environments of modern air handling units. Compatibility with Century 372 and equivalent 5-inch diameter motor specs makes it an essential stock item for emergency service calls.

• Universal Compatibility: Specifically designed as the updated version for 372, ensuring drop-in replacement without bracket modification.
• Enhanced Efficiency: Utilizes PSC motor technology for lower amperage draw (0.60/0.64 Amps) compared to older shaded-pole designs.
• Dual-Speed Flexibility: Features 1060/500 RPM operation to match the original system's static pressure requirements.
• Durable Construction: Features rolled steel housing and Class A insulation rated for a 40°C ambient temperature.
• Ready for Install: Includes the required 6 MFD 370V capacitor and 2.5" resilient rings for immediate mounting.

Is the Century 372A a direct fit for the old 372 model?
Yes, the 372A is the official 372 motor replacement. It maintains the same 42 frame size, 5-inch diameter, and electrical specifications for a seamless transition.

What are the rotation and shaft specifications?
This double shafted motor features 1/2" diameter shafts with flats. It supports CWLE (Clockwise Lead End) rotation, which is standard for most residential fan and blower assemblies.

Does this motor require a separate capacitor?
While a capacitor is required for operation, this specific 1/25 HP 115V motor typically includes the necessary 6 MFD 370V run capacitor in the box to ensure the permanent split capacitor logic functions correctly from the start.
