Overview
EN IEC 62683-1:2026 is an international standard developed by CLC and based on the updated IEC 62683-1:2026. It establishes a reference dictionary for the general description of low-voltage switchgear, controlgear, and their assemblies, focused on standardized product data and properties for electronic information exchange. The standard provides a clear, structured approach to defining device classes and their attributes to support interoperability, reliable data exchange, and effective product selection-particularly within electronic catalogues and digital product management systems.
The goal of EN IEC 62683-1:2026 is to ensure data consistency and clarity across manufacturers, suppliers, and end-users by offering standardized definitions for properties and classes of low-voltage switchgear and controlgear. This is essential for efficient business-to-business (B2B) transactions, e-catalogue creation, and e-commerce activities in the electrical and automation industries.
Key Topics
Reference Dictionary
The standard presents a comprehensive reference dictionary, including the structure of classes and properties relevant to low-voltage switchgear and controlgear and their assemblies. Terms and definitions are harmonized with related IEC publications to guarantee unambiguous interpretation and application.Standardized Product Properties
Properties are clearly named and defined, with determined value lists, formats, and units where applicable. These properties support the identification, selection, and comparison of products within electronic platforms.Device Classes and Assembly Class Structure
EN IEC 62683-1:2026 introduces new device class descriptions and expands the assembly class structure to cover a wider range of low-voltage electrical devices and assemblies, reflecting the evolving needs of the sector and responding to user and manufacturer requests.Electronic Data Exchange
The standard is designed to facilitate reliable electronic data exchange for product catalogues, reducing data misinterpretation, minimizing duplication, and supporting seamless integration into enterprise systems and supply chains.Exclusion of Manufacturer-Specific Features

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.

INTRODUCTION
Mainly large customers and wholesalers are requesting standardized product descriptions and
product properties to product manufacturers. However, all stakeholders can 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 remains
unsatisfactory for both customers and manufacturers.
In order to keep the lead of product description, IEC proposes a consistent solution within its
product standards.
The purpose of this document is to:
– define device classes and properties for low-voltage switchgear and controlgear and their
assemblies in a dedicated standard,
– provide a basis of classes of the low-voltage switchgear and controlgear and their
assemblies, and properties introduced into the IEC 61360 database maintained by
IEC/SC3D (see http://std.iec.ch/iec61360).
This document is not intended to establish a hierarchy of product classes called classification.
The intended benefits of this document are to:
– reduce the costs, 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, certificates, 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 document consists of:
– reference dictionary of low-voltage switchgear and controlgear and their assemblies using
existing terms from IEC documents. However, terminology used in e-business can be
relevant for the purpose of naming classes in this document to get a high level of
acceptance;
– properties for e-commerce purposes, conformity of properties with product standards being
the main goal of this document.
NOTE The classes "under consideration" are for information only and are intended to be completed during the next
maintenance cycle.

The description of low-voltage switchgear and controlgear and their assemblies within the
IEC 61360 database addresses the following technical aspects:
– IEC 61360 requires mandatory attributes. The complete sets of attributes for low-voltage
switchgear and controlgear and their assemblies are available in the IEC 62683DB domain
at https://cdd.iec.ch/cdd/iec62683/iec62683.nsf/TreeFrameset?OpenFrameSet. Within the
present document, only the most useful attributes are presented.
– The switchgear and controlgear and their assemblies data models are implemented in the
IEC 62683DB domain of the IEC Component Data Dictionary (CDD), by creating dictionaries
of blocks, classes and properties.

1 Scope
This part of IEC 62683 establishes the reference dictionary of the general description of classes
of low-voltage switchgear and controlgear and their assemblies based on defined properties.
This dictionary is used to facilitate the exchange in electronic format of data describing
low-voltage switchgear and controlgear, their accessories and their assemblies.
This document 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 name, and where relevant, a defined
value list, a defined format, and a defined unit.
Manufacturer specific features are not covered.
