Marley Engineered Products 3900-0362-001 Motor

The Marley Engineered Products 3900-0362-001 Motor is a high-performance OEM replacement designed for demanding industrial heating and ventilation environments. Manufactured by Emerson, this 1/10 HP HVAC motor is engineered specifically for compatibility with 480V single-phase electrical systems, commonly found in Berko and QMark unit heaters like the HUHAA2048 series. Operating at a consistent 1550 RPM, this motor provides the reliable torque necessary for fan-forced air applications while maintaining a low current draw of 0.35 amps.

Constructed with a 42Y frame and a 5-inch motor diameter, this unit features a robust Class B insulation rating for enhanced thermal protection during continuous operation. The shaft dimensions include a 1/2-inch diameter and a 4-1/4 inch length with a 1-1/2 inch flat, facilitating a secure fit for replacement blower wheels and fan blades. This stud mount motor utilizes an air-over cooling design to dissipate heat effectively, ensuring long-term duty cycles in high-demand commercial settings. Please note that a 3 MFD capacitor is required for proper startup and operation.

Key Benefits:

• OEM Compatibility: Precision-engineered for Marley, Berko, and QMark unit heaters, including model HUHAA2048.
• Technical Precision: Matches k48hxcey-132y and Dayton 23TD71 cross-references for seamless field replacement.
• High-Voltage Efficiency: Optimized for 480V 1PH industrial power supplies to reduce installation complexity.
• Industrial Construction: Features a 42Y NEMA frame and durable Class B insulation to withstand rigorous HVAC environments.
• Optimized Airflow: Delivers 1550 RPM to maintain designed CFM in fan-coil and unit heater applications.

Common Questions:

Is the capacitor included with this motor?
No, this motor requires a 3 MFD run capacitor for operation, which must be purchased separately if your existing component is out of spec.

Can this 480V motor be wired for 208V or 230V applications?
No, this is a dedicated 480V single-phase motor. Applying lower voltages will lead to torque loss and motor failure.

What is the direction of rotation for the 3900-0362-001?
This motor is designed for Clockwise (CW) rotation when viewed from the lead end/back of the motor.
