Three-phase Induction Motors

The China Energy Efficiency Labeling Implementation Regulation:GB18613-2012 has upgraded and enforced the motor efficiency class to "*GB2 class (IE3)" in a step-by-step manner since September 1, 2016.
Besides, the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment (New China RoHS Regulation) has become mandatory since July 1, 2016.

GB2 class: Efficiency class classified in the efficiency rating specified in the Chinese National Standards GB18613-2012
