The Energy Saver NEMA Premium Efficient design meets CSA-Motors and C-390, UL-Component & Insulation System Recognition and CE mark for the 320 frame and smaller.

Tested per IEEE Standard 112, Test Method B. The insulation system meets NEMA MG1-31 standards for motors operating on Inverter power at 460 or 575 volts. Includes a 10:1 variable torque along with a 4:1 constant torque speed range. The frame, end shields, fan cover and conduit box are a rugged cast iron construction. A recessed steel-reinforced neoprene slinger minimizes contaminants from entering the bearing cavity. Additional HP is available at 1.15 service factor for severe applications. A non-hygroscopic, anti-fungus Class F insulation, with an 80C (NEMA B) temperature rise. 0.08 in/sec vibration meets the IEEE 841 Standard.
