5 Siemens AG 2008AC motorsOverviewTechnical definitions4/4 Siemens pm 21 20084 Regulations, standards and specificationsThe motors comply with the appropriate standards and regula-tions, see table a result of the fact that in many countries the national regula-tions have been completely harmonized with the internationalIEC 60034-1 recommendation, there are no longer any differ-ences with respect to coolant temperatures, temperatureclasses and temperature rise motors listed below are UL-approved by "Underwriters Lab-oratories Inc.

The most common degrees of protection for AC motors in accordance with IEC 60034-5A suitable degree of protection must be selected to protect themachine against the following hazards depending on the rele-vant operating and environmental conditions: Ingress of water, dust and solid foreign objects; contact with or approach to rotating parts inside a motor and contact with or approach to live of protection of electric motors are specified by a comprises of 2 letters, 2 digits and, if required, an (International Protection)
