Design & Construction
The Open Drip Proof (ODP) enclosure protects internal windings from dripping liquids and falling debris in non-hazardous environments, making this motor well-suited for indoor mechanical rooms, air handlers, and equipment rooms. Precision ball bearings provide smooth, low-friction operation and extended service life with minimal maintenance requirements.
Electrical Versatility
With a dual-voltage rating of 208-230/460 VAC, the H155 offers wiring flexibility to match a variety of three-phase electrical services commonly found in commercial HVAC systems. The dual-frequency speed rating (3450 RPM at 60 Hz / 2850 RPM at 50 Hz) further broadens its application compatibility.
Threaded Shaft & Reversible Rotation
The threaded shaft design allows for secure coupling to driven equipment, while reversible rotation gives installers the flexibility to configure the motor for either clockwise or counterclockwise operation to meet specific system requirements.
Applications
- Commercial HVAC air handling units
- Fans and blowers
- Pumps and compressors
- Light industrial machinery
- Equipment requiring three-phase power
