Three-Phase : ODP (IP21/IP23) - NEMA Premium Efficiency
Three-Phase : ODP (IP21/IP23) - NEMA Premium Efficiency
 


Description
 
WEG Premium Efficiency motors meet or exceed all NEMA Premium and CEE requirements for energy efficiency.

These Open Drip Proof (ODP) motors are designed for environments where dirt and moisture are minimal. Design B torque and high efficiency design from 143T through 444/5T frames. These motors are specifically designed to provide maximum ventilation and heat dissipation. "C" and "D" flange available.
