29、AUTOMATIC ELECTRICAL CONTROLS Part 2-22: Particular requirements for thermal motor protectors FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of I

30、EC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS

31、) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising wit

32、h the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as ne

33、arly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in th

34、at sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications 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 uniformity, IEC National Committe

35、es undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide

36、any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest

37、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 Committees for any personal injury, property damage or other damage of any nature whatsoever, whether

38、 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 indis

39、pensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60730-

40、22 has been prepared by IEC technical committee 72: Automatic electrical controls. The text of this standard is based on the following documents: FDIS Report on voting 72/941/FDIS 72/950/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicat

41、ed in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. IEC 60730-2-22:2014 IEC 2014 5 This Part 2-22 is intended to be used in conjunction with IEC 60730-1. It was established on the basis of the fourth edition (2010) of that standard 1 . Consider

42、ation may be given to future editions of, or amendments to, IEC 60730-1. This Part 2-22 supplements or modifies the corresponding clauses in IEC 60730-1 so as to convert that publication into the IEC standard: Safety requirements for automatic electrical thermal motor protectors. Where this Part 2-2

43、2 states “addition“, “modification“, or “replacement“, the relevant requirement, test specification or explanatory matter in Part 1 should be adapted accordingly. Where no change is necessary, this Part 2-22 indicates that the relevant clause or subclause applies. In the development of a fully inter

44、national standard, it has been necessary to take into consideration the differing requirements resulting from practical experience in various parts of the world and to recognize the variation in national electrical systems and wiring rules. The “in some countries” notes regarding differing national

45、practice are contained in the following subclauses: 7.2.6 (Canada, USA) 12.2 (Canada, Japan, USA) 17.101.2.1.2 (Canada, USA) 18.1.3.101.2 (Canada, USA) BB17.205.1.2 (Canada, USA) In this publication: 1) The following print types are used: Requirements proper: in roman type; Test specifications: in i

46、talic type; Explanatory matter; in small roman type; Words defined in Clause 2: bold. 2) Subclauses, notes, tables and figures which are additional to those in part 1 are numbered starting from 101, additional annexes are lettered AA, BB, etc. A list of all parts of the IEC 60730 series, under the g

47、eneral title Automatic electrical controls for household and similar use, can be found on the IEC website. _ 1A fifth edition of IEC 60730-1 was published in 2013. 6 IEC 60730-2-22:2014 IEC 2014 The committee has decided that the contents of this publication will remain unchanged until the stability

48、 date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. IEC 60730-2-22:2014 IEC 2014 7 AUTOMATIC ELECTRICAL CONTROLS Part 2-22: Particul
