LOW-VOLTAGE SWITCHGEAR AND CONTROLGEAR ASSEMBLIES –
Part 4: Particular requirements for assemblies for construction sites (ACS)
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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 60439-4 has been prepared by subcommittee 17D: Low-voltage
switchgear and controlgear assemblies, of IEC technical committee 17: Switchgear and
controlgear.
This second edition of IEC 60439-4 cancels and replaces the first edition (1990),
amendment 1 (1995) and amendment 2 (1999). It constitutes a technical revision.
The following major changes with respect to edition 1 (including amendments 1 and 2) have
been incorporated:
– introduction of the definition for “rated current of ACS”;
– replacement of classification based on the rated current of ACS by classification based on
the function as assigned by the manufacturer;
– amended requirements for the protection of socket-outlets with reference to the more
comprehensive requirements of IEC 60364-7-704;
– introduction of common requirements for all types of ACS.
60439-4 IEC:2004 – 7 –
The text of this standard is based on the first edition, amendments 1 and 2, and the following
documents:
FDIS Report on voting
17D/301/FDIS 17D/303/RVD

voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
Assemblies for construction sites (ACS) shall comply with all requirements of IEC 60439-1
(1999) if not otherwise indicated hereinafter and shall also comply with the particular
requirements contained in this publication.
The clauses and subclauses of this standard supplement, modify or replace the respective
clauses and subclauses in IEC 60439-1:1999.
In view of the fact that this publication should be read in conjunction with IEC 60439-1, the
numbering of its clauses and subclauses correspond to the latter.
Where there is no corresponding clause or subclause in this standard, the clause or
subclause of the main document applies without modification.
Subclauses and figures which are additional to those in part 1 are numbered starting from
101.
The committee has decided that the contents of this publication will remain unchanged until
the maintenance result 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;
