MAX-E2/841™ NEMA Premium Efficiency – Inverter, Severe Duty, TEFC
MAX-E1® motors are TOTALLY ENCLOSED FAN COOLED, squirrel-cage induction motors that are designed, manufactured and tested to meet or exceed the latest NEMA, IEEE, and other international standards. All motors are CSA certified for Class I, Division II, Groups B, C, and D; temperature code T3C and have a non-sparking, non-static fan.
These motors are suitable for severe applications in environments with excessive dirt, dust and/or moisture.
The unique design, first-grade material and excellent workmanship of the MAX-E1® make TECO-Westinghouse motors last much longer and provide cost-efficent operation.
