LOW-VOLTAGE SWITCHGEAR AND CONTROLGEAR –

PRODUCT DATA AND PROPERTIES FOR INFORMATION EXCHANGE

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 62683 has been prepared by subcommittee 121A: Low-voltage

switchgear and controlgear, of the IEC technical committee 121: Switchgear and controlgear
and their assemblies for low voltage.
This second edition cancels and replaces the first edition published in 2013. This edition
constitutes a technical revision.
This present edition includes the following significant technical changes with respect to the
first edition:
a) new descriptions of 41 classes for the families of circuit-breakers and their associated
devices (ACC2xx), switches and disconnectors (ACC3xx), control switches (ACC5xx) and
terminal blocks (ACC7xx) in addition to 14 classes for motor-starters of the first edition;
b) new associated properties and value lists necessary for the new classes;
c) three new blocks of properties: ACC017 Head of the control circuit device, ACC018 Light
block of the control circuit device and ACC041 Over-current release;

– 6 – IEC 62683:2015 © IEC 2015

d) use of LEVEL_TYPE for replacing minimum and maximum properties into a single property

with two values.
The text of this standard is based on the following documents:

INTRODUCTION
Mainly large customers and wholesalers are requesting standardized product descriptions and

product properties from product manufacturers. However, all stakeholders will benefit from

this standardised presentation and data exchange.

Multiple associations or groups of actors launched different initiatives to try to respond to this

demand but, due to the lack of standardisation of classes and properties, the situation is not

satisfactory neither for customers nor for manufacturers.

In order to keep the lead of product description, IEC proposes a new consistent solution

within its product standards.
The purpose of this International Standard is to:
• define device classes and properties for low-voltage switchgear and controlgear in a
dedicated standard,
• provide a basis for introduction of the low-voltage switchgear and controlgear classes and
properties into the IEC 61360 database maintained by IEC/SC3D (see
http://std.iec.ch/iec61360).
This standard is not intended to establish a hierarchy of product classes called classification.
The intended benefits of this standard are to:
• reduce the time and efforts of mapping data for each customer request;
• optimize the workflow of B2B exchanges;
• minimize duplication of articles in customer inventories and in databases;
• minimize losses and misinterpretation of data during exchanges;
• facilitate the selection of a product, especially regarding reliability and safety;
• give access to product data everywhere regardless of country, language and culture;
• provide product data related to environmental aspects such as material declaration;
• contribute to the fast growth of the e-business by simplifying the development of:
– e-Catalogue allowing the differentiation of products performances, certifications and
approvals, etc;
– e-commerce: use of electronic networks to exchange information, products, services
and payments for commercial and communication purposes between individuals
(consumers) and businesses, between businesses themselves.

The output of this standard consists of:
• reference dictionary of low-voltage switchgear and controlgear using existing terms from
IEC standards. However, terminology used in e-business may be relevant for the purpose
of naming classes in this standard to get a high level of acceptance;
• properties for e-commerce purposes, conformity of properties with product standards
being the main goal of this standard.
NOTE The classes "under consideration" are for information only and are intended to be completed during the
next maintenance cycle.
For this project, the introduction of low-voltage switchgear and controlgear within the
IEC 61360 database needs to address the following technical aspect:
• IEC 61360 requires mandatory attributes. The complete set of mandatory attributes with
additional relevant attributes for low-voltage switchgear and controlgear will be available
within the IEC 61360 database. At the development stage, the CDD 62683 database is

– 8 – IEC 62683:2015 © IEC 2015

available at the following address:

http://std.iec.ch/cdd/iec62683/cdddev.nsf/Welcome?OpenPage . Within the present

document, only the most useful attributes will be presented;

• The switchgear and controlgear data model is implemented in an appropriate domain of

the IEC Component Data Dictionary (CDD), IEC 61360, by creating dictionaries of blocks,

classes and properties.
LOW-VOLTAGE SWITCHGEAR AND CONTROLGEAR –

PRODUCT DATA AND PROPERTIES FOR INFORMATION EXCHANGE

1 Scope
This International Standard establishes the reference dictionary of the general description of
low-voltage switchgear and controlgear classes based on defined properties.

This dictionary is used to facilitate the exchange in electronic format of data describing low-
voltage switchgear and controlgear.
This standard provides clear and unambiguous definitions of a limited number of properties
and classes which are mainly used for presentation, selection and identification of products
particularly in electronic catalogues.
Each property has an unambiguously defined meaning and naming, and where relevant, a
defined value list, a defined format and a defined unit.
The intention is not to cover manufacturer specific features.
