27、Thermal Motor Protectors, is to be used in conjunction with UL 60730-1. The requirements for thermal motor protectors are contained in this part 2 standard and UL 60730-1. Requirements of this Part 2 Standard, where stated, amend the requirements of UL 60730-1. Where a particular subclause of UL 607
28、30-1 is not mentioned in UL 60730-2-2, the UL 60730-1 subclause applies.

34、 Commission (IEC) Publication IEC 60730-2-2 are indicated by notations (differences) and are presented in bold text. There are ve types of National Differences as noted below. The difference type is noted on the rst line of the National Difference in the standard. The standard may not include all ty
35、pes of these National Differences. D1 These are National Differences which are based on basic safety principles and requirements, elimination of which would compromise safety for consumers and users of products. D2 These are national differences from IEC requirements based on existing safety practic
36、es. These requirements reect national safety practices, where empirical substantiation (for the IEC or national requirement) is not available or the text has not been included in the IEC standard. DC These are National Differences based on the component standards and will not be deleted until a part
37、icular component standard is harmonized with the IEC component standard. DE These are National Differences based on editorial comments or corrections. DR These are National Differences based on the national regulatory requirements. Each national difference contains a description of what the national
38、 difference entails. Typically one of the following words is used to explain how the text of the national difference is to be applied to the base IEC text: Addition / Add - An addition entails adding a complete new numbered clause, subclause, table, gure, or annex. Addition is not meant to include a
39、dding select words to the base IEC text. Deletion / Delete - A deletion entails complete deletion of an entire numbered clause, subclause, table, gure, or annex without any replacement text. Modication / Modify - A modication is an altering of the existing base IEC text such as the addition, replace
40、ment or deletion of certain words or the replacement of an entire clause, subclause, table, gure, or annex of the base IEC text.

41、MMISSION AUTOMATIC ELECTRICAL CONTROLS FOR HOUSEHOLD AND SIMILAR USE Part 2: Particular requirements for thermal motor protectors FOREWORD 1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC N
42、ational Committees). The object of the IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic elds. To this end and in addition to other activities, the IEC publishes International Standards. Their preparation is entrusted to technic
43、al committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. The IEC collaborates closely with the International Orga
44、nization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each tech
45、nical committee has representation from all interested National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publicat
46、ions is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international unication, IEC National Committees undertake to apply IEC International Standards transparently to the maximum extent possible in the
47、ir national and regional standards. Any divergence between the IEC Standard and the corresponding national or regional standard shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be
48、in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committee
49、s for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the
