LOW-VOLTAGE SWITCHGEAR AND CONTROLGEAR –
Product data and properties for information exchange
Part 1: Catalogue data
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.

1 INTRODUCTION
2 Mainly large customers and wholesalers are requesting standardized product descriptions and
3 product properties to product manufacturers. However, all stakeholders can benefit from this
4 standardised presentation and data exchange.
5 Multiple associations or groups of actors launched different initiatives to try to respond to this
6 demand but, due to the lack of standardisation of classes and properties, the situation is not
7 satisfactory neither for customers nor for manufacturers.
8 In order to keep the lead of product description, IEC proposes a consistent solution within its
9 product standards.
10 The purpose of this document is to:
11 • define device classes and properties for low-voltage switchgear and controlgear and their
12 assemblies in a dedicated standard,
13 • provide a basis of classes of the low-voltage switchgear and controlgear and their
14 assemblies, and properties introduced into the IEC 61360 database maintained by
15 IEC/SC3D (see http://std.iec.ch/iec61360).
16 This document is not intended to establish a hierarchy of product classes called classification.
17 The intended benefits of this document are to:
18 • reduce the costs, time and efforts of mapping data for each customer request;
19 • optimize the workflow of B2B exchanges;
20 • minimize duplication of articles in customer inventories and in databases;
21 • minimize losses and misinterpretation of data during exchanges;
22 • facilitate the selection of a product, especially regarding reliability and safety;
23 • give access to product data everywhere regardless of country, language and culture;
24 • provide product data related to environmental aspects such as material declaration;
25 • contribute to the fast growth of the e-business by simplifying the development of
26 • e-Catalogue allowing the differentiation of products performances, certificates, etc;
27 • e-Commerce : use of electronic networks to exchange information, products, services
28 and payments for commercial and communication purposes between individuals
29 (consumers) and businesses, between businesses themselves.
30 The output of this document consists of:
31 • reference dictionary of low-voltage switchgear and controlgear and their assemblies using
32 existing terms from IEC documents. However, terminology used in e-business may be
33 relevant for the purpose of naming classes in this document to get a high level of
34 acceptance;
35 • properties for e-commerce purposes, conformity of properties with product standards being
36 the main goal of this document.
37 NOTE The classes "under consideration" are for information only and are intended to be completed during the next
38 maintenance cycle.
39 The description of low-voltage switchgear and controlgear and their assemblies within the
40 IEC 61360 database needs to address the following technical aspect:
41 • IEC 61360 requires mandatory attributes. The complete sets of attributes for low-voltage
42 switchgear and controlgear and their assemblies are available in the IEC 62683DB

43 domain at https://cdd.iec.ch/cdd/iec62683/iec62683.nsf/TreeFrameset?OpenFrameSet .
44 Within the present document, only the most useful attributes are presented;
45 • The switchgear and controlgear and their assemblies data models are implemented in
46 the IEC 62683DB domain of the IEC Component Data Dictionary (CDD), by creating
47 dictionaries of blocks, classes and properties.

53 Part 1: Catalogue data
56 1 Scope
57 This document establishes the reference dictionary of the general description of classes of low-
58 voltage switchgear and controlgear and their assemblies based on defined properties.
59 This dictionary is used to facilitate the exchange in electronic format of data describing low-
60 voltage switchgear and controlgear, their accessories and their assemblies.
61 This document provides clear and unambiguous definitions of a limited number of properties
62 and classes which are mainly used for presentation, selection and identification of products
63 particularly in electronic catalogues.
64 Each property has an unambiguously defined meaning and naming, and where relevant, a
65 defined value list, a defined format and a defined unit.
66 The intention is not to cover manufacturer specific features.
