Century Motors 346 Motor

The Century Motors 346 is a versatile 1/8-1/10 HP HVAC replacement motor designed for reliable continuous duty in residential and light commercial air handling equipment. Operating at 115 Volts, this single-phase shaded pole motor features a dual-speed configuration with a maximum 1050 RPM, making it a critical component for furnace blowers and attic ventilators. Built with a NEMA 42 frame size (5-inch diameter) and an Open Air Over (OAO) enclosure, it ensures optimal heat dissipation during operation. The motor is equipped with sleeve bearings and a 1/2" x 4 1/2" shaft, supporting CCW Lead End (CCWLE) rotation. This model is technically identical to the 26-346 and serves as a direct drop-in for various OEM blower motor applications, including specific Coleman and Nordyne units. Professional contractors value the automatic thermal overload protection and the availability of tapped holes for Coleman mounting, ensuring a secure and efficient field installation.

• Dual-Speed Logic: Supports 2-speed operation (4.8/3.3 Amps) for precise airflow control in various furnace blower applications.
• OEM Compatibility: Replaces common part numbers including 26-346, GE 2981, and Nordyne 901375 for seamless retrofitting.
• Thermal Protection: Integrated automatic overload protector prevents winding failure during restricted airflow or high-ambient conditions.
• Robust Construction: Features rolled steel frame and sleeve bearings designed for quiet, long-term continuous duty cycles.

• What are the primary applications for the Century 346? This motor is primarily utilized in HVAC air handlers, furnace blowers, and attic ventilators requiring a 5-inch diameter motor.
• Is this a direct replacement for the 26-346? Yes, the Century 346 and 26-346 share the same electrical specifications, frame dimensions, and rotation.
• How is motor rotation determined? Rotation for this unit is CCW Lead End, which is equivalent to CW Shaft End when viewed from the opposite side.
