Overview
EN IEC 61293:2020 (IEC 61293:2019) specifies minimum requirements and general rules for marking electrical equipment with ratings related to the electrical supply. It is a horizontal standard intended to ensure consistent, visible and unambiguous markings of supply-related characteristics (voltage, current, frequency, power, etc.) so that equipment can be safely selected, installed and operated. This edition is a technical revision of the 1994 standard and is aligned with IEC Guide 108.
Key topics and requirements
- Scope and purpose: Defines general marking requirements for characteristics related to any supply system and provides uniform methods for technical committees and manufacturers.
- Marking requirements: Basic rules on how characteristics and rated values must be shown on equipment and in technical documentation.
- Representation of values: Guidance for single values, limit values, multiple values, ranges and tolerances to ensure clarity and consistency.
- Visibility: New provision to consider the visibility of markings during normal operation.
- Range and set values: More detailed requirements where equipment has a set or a range of rated values for a given characteristic.
- Documentation: Requirement to provide corresponding markings in technical documentation (manuals, datasheets).
- Consistency and presentation: Rules to ensure consistent sequence and presentation of rated values and other characteristics.
- Annexes: Informative examples (Annex A) and country-specific notes (Annex B).
- Relationship to EU law: Annex ZZ links the standard to safety objectives of Directive 2014/35/EU (Low Voltage Directive) for presumption of conformity where applicable.
Practical applications
EN IEC 61293:2020 is practical for:
- Ensuring that electrical equipment is clearly and correctly labeled for safe connection to electrical supply systems.
- Harmonizing product marking across product families and standards to reduce installer errors and safety risks.
- Improving documentation accuracy by requiring matching markings in manuals and datasheets.
- Supporting conformity assessment and regulatory compliance (e.g., CE marking under the Low Voltage Directive where referenced).
Who uses this standard
- Technical committees developing product standards (to reference consistent marking rules).
- Manufacturers applying markings to products, sub-assemblies and components.
- Design and safety engineers, installers and maintenance personnel who rely on clear supply ratings.
- Regulatory bodies and conformity assessors verifying that supply-related markings meet safety and documentation requirements.

MARKING OF ELECTRICAL EQUIPMENT WITH RATINGS RELATED
TO ELECTRICAL SUPPLY – SAFETY REQUIREMENTS
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 61293 has been prepared by IEC technical committee 3:
Information structures and elements, identification and marking principles, documentation and
graphical symbols.
This second edition cancels and replaces the first edition published in 1994. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) its status as a basic safety publication has been removed, and it has become a horizontal
publication in accordance with IEC Guide 108;
b) the scope is extended to include the applicability of this document to product
manufacturers;
c) the addition of a provision that the visibility of the marking during normal operation should
be considered;
SIST EN 61293:2020
– 4 – IEC 61293:2019 © IEC 2019
d) more detailed requirements where equipment has a set or range of rated values for a
given characteristic;
e) requirements regarding the provision of the markings also in the technical documentation
have been added;
f) some notes have been converted to normative text;
g) normative references and references to other standards have been updated.
The text of this International Standard is based on the following documents:
FDIS Report on voting
3/1404/FDIS 3/1414/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 document has been drafted in accordance with the ISO/IEC Directives, Part 2.
It has the status of a horizontal standard in accordance with IEC Guide 108.
The reader's attention is drawn to the fact that Table B.1 of Annex B lists all of the "in-some-
country" clauses on differing practices of a less permanent nature relating to the subject of
this standard.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to
the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,

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.
