31、mpressors of hermetic and semi-hermetic type 1 Scope and normative references This clause of Part 1 is applicable except as follows: 1.1 Replacement: 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

32、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 mo

33、tor 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. 1.1.1 This standard applies to the inherent safety, to the operating values, operating times,

34、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 60335-2-3

35、4. Throughout this standard the word “equipment“ means “appliance and equipment“. 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

36、 farms, are within the scope of this standard. This standard does not apply to thermal motor protectors designed exclusively for industrial applications. 1.1.2 This standard does not apply to other means of motor protection. 1.1.3 This standard does not apply to a manual device for opening the circu

38、 rated output of 11 kW or less. Controls complying with the requirements of this standard are considered to comply with the requirements of IEC 60730-2-21). 1.3 Replacement: This standard does not take into account the response value of an automatic action of a control, if such a response value is d

39、ependent upon the method of mounting the control in the equipment. Where a response value is of significant purpose for the protection of the user, or surroundings, the value defined in the appropriate household equipment standard or as determined by the manufacturer applies. 1.5 Normative reference
