3-101: Subracks and associated plug-in units –
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) IEC draws attention to the possibility that the implementation of this document may involve the use
of (a) patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed
patent rights in respect thereof. As of the date of publication of this document, IEC [had/had not]
received notice of (a) patent(s), which may be required to implement this document. However,
implementers are cautioned that this may not represent the latest information, which may be obtained
from the patent database available at https://patents.iec.ch. IEC shall not be held responsible for
identifying any or all such patent rights.

IEC 60297-3-101 has been prepared by subcommittee 48D: Mechanical structures for electrical and
electronic equipment, of IEC technical committee. It is an International Standard.
This second edition cancels and replaces the first edition published in 2004. This edition constitutes a
technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
This edition was created based on the technological schemes of entire modular structure of the 19 in
standards IEC 60297-3-XXX series which is clarified by IEC TR 60297-3-1:2023.
