Foreword
The text of document 17B/1821/FDIS, future edition 2 of IEC 60947-5-3, prepared by SC 17B "Low-
voltage switchgear and controlgear" of IEC/TC 17 "Switchgear and controlgear" was submitted to the
IEC-CENELEC parallel vote and approved by CENELEC as EN 60947-5-3:2013.
The following dates are fixed:
– latest date by which the document has to be implemented at (dop) 2014-06-10
national level by publication of an identical national
standard or by endorsement
– latest date by which the national standards conflicting with (dow) 2016-09-10
the document have to be withdrawn

This document supersedes EN 60947-5-3:1999.
EN 60947-5-3:2013 includes the following significant technical changes with respect to
EN 60947-5-3:1999:
a) general principles of EN 61508 series;
b) classification according to the requirements of EN 62061;
c) classification according to EN ISO 13849-1.
This European Standard is to be read in conjunction with EN 60947-1, Low-voltage switchgear and
controlgear – Part 1: General rules and EN 60947-5-2, Low-voltage switchgear and controlgear –
Part 5-2: Control circuit devices and switching elements - Proximity switches. The provisions of Part 1
and Part 5-2 are only applicable to this European Standard where specifically called for. The
numbering of the subclauses of this European Standard is sometimes not continuous because it is
based on the numbering of the subclauses of EN 60947-1 or EN 60947-5-2.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CENELEC [and/or CEN] shall not be held responsible for identifying any or all such
patent rights.
This document has been prepared under a mandate given to CENELEC by the European Commission
and the European Free Trade Association, and supports essential requirements of EU Directive(s).
For the relationship with EU Directive(s), see informative Annex ZZ, which is an integral part of this
document.
This European Standard does not deal with any specific requirements on noise as the noise emission
of control circuit devices and switching elements is not considered to be a relevant hazard.

(informative)

Coverage of Essential Requirements of EC Directives
This European Standard has been prepared under a mandate given to CENELEC by the European
Commission and the European Free Trade Association to provide one means of conforming to
Essential Requirements of the New Approach Directive for machinery 2006/42/EC.
Once this standard is cited in the Official Journal of the European Union under that Directive,
compliance with the normative clauses of this standard confers, within the limits of the scope of this
standard, a presumption of conformity with essential requirements as given in Annex I, 1.2.1 of that

LOW-VOLTAGE SWITCHGEAR AND CONTROLGEAR –

Part 5-3: Control circuit devices and switching elements –
Requirements for proximity devices with defined
behaviour under fault conditions (PDDB)

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 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) 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 with 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 nearly 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 that 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 Committees 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 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 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 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 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 60947-5-3 has been prepared by subcommittee 17B: Low-voltage
switchgear and controlgear, of IEC technical committee 17: Switchgear and controlgear.
This second edition replaces the first edition published in 1999 and its amendment published
in 2005. It is a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) general principles of IEC 61508 series;
b) classification according to the requirements of IEC 62061;
c) classification according to ISO 13849-1.
This standard is to be read in conjunction with IEC 60947-1, Low voltage switchgear and
controlgear – Part 1: General rules and IEC 60947-5-2, Low-voltage switchgear and

---------------------- Page: 14 ----------------------

controlgear – Part 5-2: Control circuit devices and switching elements – Proximity switches.
The provisions of Part 1 and Part 5-2 are only applicable to this standard where specifically
called for. The numbering of the subclauses of this standard is sometimes not continuous
because it is based on the numbering of the subclauses of IEC 60947-1 or IEC 60947-5-2.
The text of this standard is based on the following documents:
FDIS Report on voting
17B/1821/FDIS 17B/1826/RVD

Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all parts in the IEC 60947 series, published under the general title Low-voltage
switchgear and controlgear, can be found on the IEC website.
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 publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
