NEN-EN-IEC 60730-2-22  applies to the partial evaluation of thermal motor protectors asdefined in IEC 60730-1 for household and similar use, including heating, air conditioning andsimilar applications as well as for sealed (hermetic and semi-hermetic type) motorcompressors.NOTE A thermal motor protector is considered an integrated control since its protective functionality isdependent on the correct mounting and fixing in or on a motor and which can only be fully tested in combinationwith the relevant motor. This dependency is illustrated by:• the ability of the thermal motor protector to accurately and reliably sense the heat of the motor windings;thus, addressing the over-temperature protection due to motor overload conditions;• the ability of the thermal motor protector to accurately and reliably sense the current due to motor lockedrotorconditions; thus, reducing the response time and not being adversely affected by heat-sink at theassembly spot in the application;• the influence of the motor’s electromagnetic field on the switch behaviour of the thermal motor protector;particularly, affecting the arc direction between the contacts resulting in uneven wear of the contact materialand eventually leading to failure of operation.Requirements concerning the testing of the combination of sealed (hermetic and semihermetictype) motor-compressors and thermal motor protectors are given inIEC 60335-2-34.
