Three-phase Induction Motors

The Commission Regulation (EC) No.640/2009 has upgraded and enforced the motor efficiency class to IE3* (IEC60034-30-1:2014) in a step-by-step manner since January 1, 2015.
To comply with the New Legislative Framework (NLF),
the EU Directive was revised and the new Low Voltage Directive (2014/35/EU) has become mandatory since April 20, 2016.

IE3: Efficiency class (IE code) based on the international standard IEC 60034-30-1:2014
