 N 60730-2-2

Annotation

This clause of Part 1 is replaced by the following:

This part of IEC 60730 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.

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 protector are given in annex AA for information and include requirements taken from other IEC standards.

This part of IEC 60730 applies to thermal motor protectors using thermistors (NTC, PTC), additional requirements for which are contained in annex J of part 1.

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 household or similar equipment.

This standard is also applicable to thermal motor protectors for appliances within the scope of IEC 60335-1.

Throughout this standard, the word "equipment" means "appliance and equipment".

Throughout this standard, the words "not applicable" mean that the test is not applicable to the evaluation of the thermal motor protector submitted separately. However, the test may be applicable to the evaluation of the thermal motor protector in combination with the motor.
