1 INTRODUCTION
3 The growing use of protection devices (e.g. miniature circuit-breakers as defined in IEC 60898-1), and
4 the need to go toward more digital tools and processes requires the description of such devices to be
5 made available in the most adequate digital format.
6 To serve as a reference in this effort of standardisation, the IEC provides a support for gathering all
7 contributions for devices descriptions under the IEC Common Data Dictionary (IEC CDD).
8 Such a work at IEC level aims to provide for the protection devices an unambiguous semantic,
9 consistent with its product standard, made available for use on the market by the various stakeholders.
10 The intended benefits of this document are to:
11 • reduce the costs and efforts in mapping data for each customer request;
12 • optimize the workflow of B2B exchanges;
13 • minimize duplication of articles in customer inventories and in databases;
14 • minimize losses and misinterpretation of data during exchanges;
15 • facilitate the selection of a product, especially regarding reliability and safety;
16 • give access to product data everywhere regardless of country, language and culture;
17 • provide product data related to environmental aspects such as environmental declaration;
18 • contribute to the fast growth of e-business by simplifying the development of
19 - e-catalogue allowing the differentiation of products performances, certificates, etc;
20 - e-commerce: use of electronic networks to exchange information, products, services and
21 payments for commercial and communication purposes between individuals (consumers) and
22 businesses, and between businesses themselves.
23 • enable new e-business models
25 The output of this document is a reference dictionary for protection devices considered in sub-
26 committee 23E for use in e-commerce, in software and in any application for product selection.
27 This work is done in close collaboration between SC 23E and SC 3D which in charge of the
28 maintenance of the application IEC CDD.
30 The modifications applied to the CD version are about:
31 - information arrangement in the document. Some elements (reminders) are moved to a
32 new annex
33 - change of class names applied to KDA021, KDA022, KDA023
34 - specialized blocks are removed from the blocks list
35 - new properties (KDB021 & KDD108), representing the ‘’number of switched poles’’,
36 were created and replace properties that were reused from TC 121 (number of poles)
37 - two properties from TC 121 are added to complete the classes descriptions (provision
38 for locking, rated impulse withstand voltage)

41 1. Scope
42 The purpose of this document is to draft product classes and properties, representing the MCB
43 (Miniature Circuit-Breaker), to become a part of the IEC 63508 DB. It includes data needed for product
44 selection as well as data needed for engineering.
45 This IEC 63508 DB intends, as a contribution to the IEC Common Data Dictionary, to be used by
46 catalogue consortia, other database standards and software as a data reference for Circuit-breakers
47 and similar equipment for household use.
48 Note: In the future, it is intended to extend the IEC 63508 DB to other type of products managed by IEC/SC 23E.

118 IEC Common Data Dictionary
119 IEC CDD
120 IEC CDD is an International Standard (IEC 61360-4 DB) and serves as a common product data
121 dictionary for all industrial/technical domains (electrotechnical and non-electrotechnical; e.g.
122 industry, building, energy, healthcare, …) based on the methodology and the information model of
123 IEC 61360 series, and provides
124 • unambiguous identification of classes and properties, and their relations;
125 • commonly accepted terminology and definitions based on accepted sources such as IEC
126 International Standards, other International Standards, industry standards, or public
127 authorities;
128 • hierarchies of concepts enabling users to appropriately characterize their products and
129 services;
130 • relevant conditions and constraints, if necessary, on possible values of characteristics;
131 • technical representation of concepts including units and data types and their identification.
135 4. Data formats description
136 IEC 61360 series are the reference documents describing the different formats that are intended to be
137 used for a product’s description.
138 To assist readers of this standard, a selection of useful definitions for data formats and concepts (taken
139 from IEC 61360-1) is available in annex A.
141 5. Overview of the structure of this domain
IEC CDV 63508 © IEC 2024 5 23E/1349/CDV
142 This document aims to initiate a domain to become a contribution to the IEC CDD.
143 This domain is a collection of properties and blocks of properties to describe the products identified in
144 this first approach focused on miniature circuit-breakers.
145 This domain will be completed in a further stage by properties necessary to describe other products
146 from IEC SC 23E.
147 It is noted that another domain named “Low voltage switchgear and controlgear (IEC 62683)” is
148 published in IEC CDD by IEC/TC 121. This domain does not include miniature circuit-breakers (MCB).
149 To avoid duplicated properties it is intended to re-use existing properties and blocks from the domain
150 “Low voltage switchgear and controlgear (IEC 62683)” in the new domain for miniature circuit -breakers,
151 wherever applicable. Such re-used blocks or properties have identifiers (ID) starting with ACC or ACE.
153 6. Device classes
154 6.1. Device class attributes
155 The attributes of the device class shall follow IEC 61360-1.
156 The following attributes of a device class are considered in this standard: identifier, preferred name,
157 definition, synonymous name and source document.
158 NOTE The synonymous names are limited to those necessary to avoid confusion when selecting a device class.
160 6.2. Classification of circuit-breakers and similar equipment for household use
161 The following table gives the classification of circuit-breakers and similar equipment for household use
162 domain based on the corresponding product standards. The class name column is structured in four
163 levels of hierarchy using indent alignments.
