This part of IEC 60730 applies to the partial evaluation of thermal motor protectors as defined in IEC 60730-1 for sealed (hermetic and semi-hermetic type) motor-compressors. A thermal motor protector is an integrated control which is dependent on its correct mounting and fixing in or on a motor and which can only be fully tested in combination with the relevant motor. Requirements concerning the testing of the combination of motor and thermal motor protectors are given in IEC 60335-2-34. This standard applies to thermal motor protectors for motor compressors using NTC or PTC thermistors, additional requirements for which are contained in Annex J. This standard applies to the inherent safety, to the operating values, operating times, and operating sequences, where such are associated with equipment safety, and to the testing of thermal motor protectors used in or on sealed (hermetic and semi-hermetic type) motor-compressors. This standard applies to thermal motor protectors for motor-compressors within the scope of IEC 60335-2-34. Thermal motor protectors for motor compressors not intended for normal household use, but which nevertheless may be used by the public, such as equipment intended to be used by laymen in shops, in light industry and on farms, are within the scope of this standard. This standard does not apply to thermal motor protectors designed exclusively for industrial applications.
