IEC 60034-30-1:2014
This standard defines four International Efficiency (IE) classes for single speed electric motors that are rated according to IEC 60034-1 or IEC 60079-0 (explosive atmospheres) and designed for operation on sinusoidal voltage.

– IE4 = Super premium efficiency
– IE3 = Premium efficiency, identical to the table in 10CFR431 (‘NEMA Premium’) in the USA and CSA C390-10:2015 for 60 Hz
– IE2 = High efficiency
– IE1 = Standard efficiency

IEC 60034-30-1 covers the power range from 0.12kW up to 1000 kW. Most of the different technical constructions of electric motors are covered as long as they are rated for direct on-line operation. The coverage of the standard includes:

– Single speed electric motors (single and three-phase), 50 and 60 Hz
– 2, 4, 6 and 8 poles
– Rated output PN from 0.12 kW to 1000 kW
– Rated voltage UN above 50 V up to 1 kV
– Motors capable of continuous operation at their rated power with a temperature rise within the specified insulation temperature class
– Motors, marked with any ambient temperature within the range of -20 °C to +60 °C
– Motors, marked with an altitude up to 4000 m above sea level
