A new edition of IEC 60730-2-22 has been published by the International Electrotechnical Committee. IEC 60730-2-22 applies to “Automatic electrical controls – Part 2-22: Particular requirements for thermal motor protectors.” The new edition is available for purchase on the IEC website.

Description*

IEC 60730-2-22:2014 applies to the partial evaluation of thermal motor protectors as defined in IEC 60730-1 for household and similar use, including heating, air conditioning and similar applications as well as for sealed (hermetic and semi-hermetic type) motor-compressors. A thermal motor protector is considered an integrated control since its protective functionality is dependent on the correct mounting and fixing in or on a motor and which can only be fully tested in combination with the relevant motor.”
