Overview

EN 62683-1:2017 (IEC 62683-1:2017) - Low-voltage switchgear and controlgear - Part 1: Catalogue data - defines a standardized, machine-readable product data dictionary for low‑voltage switchgear and controlgear. The standard establishes a reference set of classes and unambiguous properties (names, meanings, value lists, formats and units) to facilitate reliable electronic information exchange between manufacturers, distributors, catalogue systems and software tools. It is explicitly focused on generic product description for presentation, selection and identification in electronic catalogues and is not intended to capture manufacturer‑specific features.

Key Topics and Requirements

• Reference dictionary of device classes: standardized device classes for circuit‑breakers, switches, contactors, motor starters, control switches and many related components.
• Defined properties and attributes: each property is given an unambiguous name, definition, and - where relevant - a controlled value list, data format and unit to ensure consistency.
• Property blocks and device class attributes: structures for grouping related properties and specifying attributes for each device class to support catalogue presentation and selection logic.
• Criteria for naming and attributes: rules for how properties are named and the metadata required for each property to enable interoperable electronic exchange.
• Interoperability focus: intended to support electronic catalogues, product selection tools and automated data interchange between systems.
• Normative references: aligns with related IEC/CENELEC publications (examples in the standard include IEC 61360‑1 and relevant parts of the IEC 60947 series).

Practical Applications - Who Uses It and Why

• Manufacturers and catalogue managers: create consistent, searchable product data for online catalogues and authorization to sell across markets.
• Distributors and e‑commerce platforms: ingest standardized product records to improve search, filtering and cross‑vendor comparison.
• Software integrators and data engineers: map product data to ERP, PIM, PLM or specification tools for automated workflows and accurate BOM generation.
• Specifiers and system designers: rely on consistent attribute definitions for precise product selection and interoperability in procurement processes.
• Standards bodies and test houses: reference a common vocabulary for documentation and conformity activities.

Related Standards

• IEC 61360‑1 (standard data element types / classification scheme)
• IEC 60947 series (low‑voltage switchgear and controlgear general rules and device standards)
• Harmonized EN versions as listed in the standard (CENELEC adoption of IEC text)

Using EN 62683-1:2017 helps organizations achieve reliable, repeatable electronic product data exchange for low‑voltage switchgear and controlgear - reducing errors, speeding quotation and selection processes, and improving catalogue interoperability.

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.

INTRODUCTION
Mainly large customers and wholesalers are requesting standardized product descriptions and
product properties to product manufacturers. However, all stakeholders will benefit from this
standardized 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 standardization 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 document 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 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 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, and between businesses themselves.
The output of this document 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 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.
For this project, the introduction of low-voltage switchgear and controlgear within the
IEC 61360 database needs to address the following technical aspects:
• 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
available at the following address:

IEC 62683-1:2017 © IEC 2017 – 9 –
https://cdd.iec.ch/cdd/iec62683/iec62683.nsf. 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 –

Part 1: Catalogue data
1 Scope
This document 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 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 naming, and, where relevant, a
defined value list, a defined format and a defined unit.
The intention is not to cover manufacturer-specific features.

3.1
attribute
data element for description of a property, a relation or a device class
EXAMPLE The name of a property, the code of a class, the unit of measure of a property

IEC 62683-1:2017 © IEC 2017 – 11 –
3.2
block (of properties)
collection of properties describing one common aspect of the device class
Note 1 to entry: A block is a feature class in the sense of IEC 61360-1 and ISO 13584-42.
EXAMPLE Diagnostic functions, control circuit.
3.3
cardinality
pattern defining the number of times a concept reoccurs within a description
Note 1 to entry: Cardinality allows a block of properties contained in a list of properties to be used more than
once for a particular transaction in order to describe, for example, a device with several different outputs or more
than one process case.
Note 2 to entry: Cardinality is defined by IEC 61987-10.
3.4
device
material element or assembly of such elements intended to perform a required function
