47 FOREWORD
48 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
49 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote intern ational
50 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
51 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
52 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
53 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
54 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
55 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
56 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
57 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
58 consensus of opinion on the relevant subjects since each technical committee has representation from all
59 interested IEC National Committees.
60 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
61 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
62 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
63 misinterpretation by any end user.
64 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
65 transparently to the maximum extent possible in their national and regional publications. Any divergence between
66 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
67 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
68 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
69 services carried out by independent certification bodies.
70 6) All users should ensure that they have the latest edition of this publication.
71 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
72 members of its technical committees and IEC National Committees for any personal injury, property damage or
73 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
74 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
75 Publications.
76 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
77 indispensable for the correct application of this publication.
78 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
79 rights. IEC shall not be held responsible for identifying any or all such patent rights.
80 International Standard IEC 62626-1 has been prepared by subcommittee SC121A: Low-voltage
81 switchgear and controlgear, of IEC technical committee 121: Switchgear and controlgear.
82 The text of this standard is based on the following documents:

84 Full information on the voting for the approval of this standard can be found in the report on
85 voting indicated in the above table.
86 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
87 A list of all parts in the IEC 62626 series, published under the general title Low-voltage
88 switchgear and controlgear enclosed equipment, can be found on the IEC website.

98 INTRODUCTION
99 Enclosed switch-disconnectors covered by this part of IEC 62626 are intended for use in various
100 applications, to provide isolation of electrical equipment, especially motor circuits, during repair,
101 cleaning and maintenance works.
102 Such enclosed switch-disconnectors are sometimes known as “maintenance switches”, or
103 “safety switches”. The name “safety switch” is also used for safety related position switches,
104 inspection switches and switches for other ap
