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 61439-7 has been prepared by subcommittee 121B: Low-voltage

switchgear and controlgear assemblies, of IEC technical committee 121: Switchgear and

controlgear and their assemblies for low voltage.

This first edition cancels and replaces the relevant technical specification published in 2014. It

constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

technical specification:

a) a new classification of the stationary ASSEMBLIES in accordance with their mechanical

resistance (5.702);

b) a new Table 702 with the list of tests and relevant severities to which the ASSEMBLIES have

to be subjected according to the classification mentioned at point a);
---------------------- Page: 5 ----------------------
– 4 – IEC 61439-7:2018 © IEC 2018

c) a new Annex (CC) with a new endurance test for the individual switching devices intended

to be used in AEVSC, if they have not already been tested against this requirement;

d) a general editorial review and a technical revision.
The text of this standard is based on the following documents:
FDIS Report on voting
121B/74/FDIS 121B/77/RVD

Full information on the voting for the approval of this International Standard can be found in

the report on voting indicated in the above table.

This standard is to be read in conjunction with IEC 61439-1:2011. The provisions of the

general rules dealt with in IEC 61439-1:2011 are applicable to this standard where they are

specifically cited. When this document states "addition", "modification" or "replacement", the

relevant text in IEC 61439-1:2011 is to be adapted accordingly.

Subclauses that are numbered with a 701 (702, 703, etc.) suffix are additional to the same

subclause in IEC 61439-1:2011.
Tables and figures in this document that are new are numbered starting with 701.
New annexes in this document are lettered AA, BB, etc.

In this standard, the term ASSEMBLY written in small capitals is defined in 3.1.1 of IEC 61439-

1:2011.

The reader’s attention is drawn to the fact that Annex EE lists all of the "in-some-country"

clauses on differing practices of a less permanent nature relating to the subject of this

standard

A list of all parts of the IEC 61439 series, under the general title Low-voltage switchgear and

controlgear assemblies, can be found on the IEC website.
