15、 IEC:1997+A.1:1998 5 INTERNATIONAL ELECTROTECHNICAL COMMISSION_ELECTRICAL ACCESSORIES PORTABLE RESIDUAL CURRENT DEVICES WITHOUT INTEGRALOVERCURRENT PROTECTION FOR HOUSEHOLDAND SIMILAR USE (PRCDs)FOREWORD1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardiz
16、ation comprisingall national electrotechnical committees (IEC National Committees). The object of the IEC is to promoteinternational co-operation on all questions concerning standardization in the electrical and electronic fields. Tothis end and in addition to other activities, the IEC publishes Int
17、ernational Standards. Their preparation isentrusted to technical committees; any IEC National Committee interested in the subject dealt with mayparticipate in this preparatory work. International, governmental and non-governmental organizations liaisingwith the IEC also participate in this preparati
18、on. The IEC collaborates closely with the International Organizationfor Standardization (ISO) in accordance with conditions determined by agreement between the twoorganizations.2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, aninternational conse
19、nsus of opinion on the relevant subjects since each technical committee has representationfrom all interested National Committees.3) The documents produced have the form of recommendations for international use and are published in the formof standards, technical reports or guides and they are accep
20、ted by the National Committees in that sense.4) In order to promote international unification, IEC National Committees undertake to apply IEC InternationalStandards transparently to the maximum extent possible in their national and regional standards. Anydivergence between the IEC Standard and the c
21、orresponding national or regional standard shall be clearlyindicated in the latter.5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment declared to be in conformity with one of its standards.6) Attention is drawn to the possibility tha
22、t some of the elements of this International Standard may be the subjectof patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.International Standard IEC 61540 has been prepared by subcommittee 23E: Circuit-breakersand similar equipment for household us
23、e, of IEC technical committee 23: Electrical accessories.This consolidated version of IEC 61540 is based on the first edition (1997) documents23E/263/FDIS and 23E/305/RVD and its amendment 1 (1998) documents 23E/355/FDIS and23E/361/RVD.It bears the edition number 1.1.A vertical line in the margin sh

26、s to portable devices for household and similar uses(hereafter referred to as portable residual current devices (PRCDs), consisting of a plug, aresidual current device (RCD) and one or more socket-outlets or a provision for connection,functionally independent of, or functionally dependent on, line v
27、oltage. They do not incorporateovercurrent protection. They are intended for single-phase circuits for rated currents notexceeding 16 A for rated voltages not exceeding 250 V a.c., or for rated current not exceeding32 A for rated voltages not exceeding 130 V a.c. to earth. They are intended to provi
28、deprotection against shock hazard in case of direct contact, in addition to the protection providedby the fixed installations for the circuit downstream.PRCDs have a rated residual operating current not exceeding 0,03 A.They ensure tripping in case of residual alternating currents and residual pulsa
29、ting directcurrents, whether suddenly applied or slowly rising (see 8.15).Plugs and socket-outlets will comply with the relevant standards.This standard applies to portable devices performing simultaneously the functions of detectionof the residual current, of comparison of the value of this current
30、 with the residual operatingvalue and of opening of the protected circuit when the residual current exceeds this value.They are not intended to be used as parts of fixed installations. Their connecting means maybe plugs, socket-outlets, terminals or cords.NOTE 1 The requirements for PRCDs are in lin
31、e with the general requirements of IEC 61008-1. PRCDs areessentially intended to be operated by unskilled persons and designed not to require maintenance. They may besubmitted for certification purposes.NOTE 2 The RCD part of the PRCD is not intended to provide isolation which may be provided by the
32、 plug.NOTE 3 The use of an integral fuse is permitted, if necessary, for the relevant plug and socket-outlet system.NOTE 4 In Australia and in Germany, PRCDs switching also the PE circuit are in use. Such devices are notcovered by this standard.The requirements of this standard apply for environment
33、al conditions as defined in 7.1.Additional requirements may be necessary for PRCDs used in locations having more severeenvironmental conditions.PRCDs including batteries are not covered by this standard.The present standard does not contain additional requirements for PRCDs without earthingcontacts
34、for which specific requirements may apply. It may, however, be used as a guide forsuch devices which are intended to be used only with Class II appliances.The present standard does not apply to PRCDs providing the additional function of detectingfaults on the supply side and avoiding the closing of
35、the PRCD on a faulty supply circuit.SANS 61540:2007This s tandard may only be used and printed by approved subscription and freemailing clients of the SABS .61540 IEC:1997+A.1:1998 9 2 Normative referencesThe following normative documents contain provisions which, through reference in this text,cons
