27、s for exterior and interior signs and luminaires FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation o
28、n 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) and Guides (hereafter referred to as “IEC P
29、ublication(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 with the IEC also participate in this preparation
30、 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 nearly as possible, an international consensus o
31、f 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 that sense. While all reasonable efforts are mad
32、e 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 Committees undertake to apply IEC Publications transpa
33、rently 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 any attestation of conformity. Independent cer
34、tification 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 edition of this publication. 7) No liability s
35、hall 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 direct or indirect, or for costs (including l
36、egal 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 p
37、ublication. 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 60669-2-6 has been prepared by subcommittee 23B: Plu
38、gs, socket-outlets and switches, of IEC technical committee 23: Electrical accessories. The text of this standard is based on the following documents: CDV Report on voting 23B/990/CDV 23B/1032/RVC Full information on the voting for the approval of this standard can be found in the report on voting i
39、ndicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. 60669-2-6 IEC:2012 5 This part of IEC 60669 is to be used in conjunction with IEC 60669-1:1998, Amendment 1:1999 and Amendment 2:2006. It lists the changes necessary to convert that stan
40、dard into a specific standard for firemans switches. In this publication, the following print types are used: requirements proper: in roman type; test specifications: in italic type; notes: in smaller roman type. Subclauses, figures tables or notes which are additional to those in part 1 are numbere
41、d starting from 101. A list of all the parts in the IEC 60669 series, published under the general title Switches for household and similar fixed electrical installations, can be found on the IEC website. The following differing practices exist in the countries indicated below. Clause 1: in all CENEL
42、EC countries, the rated voltage for the signs and luminous-discharge-tube installations is higher than 1 kV but lower than 10 kV and these should be in accordance with EN 50107 series. Clause 1: in Italy, installation rules and/or laws may require different protection switching devices in order to c
43、omply with the function given in the scope of this standard. Subclause 13.108: in France, the enclosure of the firemans switch and of the actuating handle could be of another colour than red if the firemans switch is equipped with a red illuminated indicator according to 13.107. The colours yellow,
44、green and blue are not allowed (according to ISO 3864-1:2002). The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the
45、 publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 6 60669-2-6 IEC:2012 SWITCHES FOR HOUSEHOLD AND SIMILAR FIXED ELECTRICAL INSTALLATIONS Part 2-6: Particular requirements Firemans switches for exterior and interior signs and luminaires 1 Scope This clause of Par
46、t 1 is applicable except as follows: Replacement of the first paragraph by: This part of IEC 60669 is applicable to firemans switches used for the breaking of the low-voltage circuits for exterior and interior signs and luminaires e.g. neon signs for a.c. only with a rated voltage not exceeding 440
47、V and a rated current not exceeding 125 A. NOTE 101 In the following countries, the rated voltage for the signs and luminous-discharge-tube installations is higher than 1 kV but lower than 10 kV and these should be in accordance with EN 50107 series: all CENELEC countries. Replacement of the 6thpara
48、graph and Note 6 by the following paragraph and new notes: Firemans switches complying with this standard are suitable for use between 25 C and +70 C. NOTE 102 Firemans switches are designed for overvoltage category III and used in environment of pollution degree 2 according to IEC 60664-1. NOTE 103
49、 In the following country installation rules and/or laws may require different protection switching devices in order to comply with the function given in the scope of this standard: IT. 2 Normative references This clause of Part 1 is applicable with the following additions: IEC 60669-1:1998, Switches for household and similar fixed electrical installations Part 1: General requirements A
