Miniature fuses - Part 1: Definitions for miniature fuses and general requirements for miniature fuse-links
IEC 60127-1:2023 is available as IEC 60127-1:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60127-1:2023 covers the general requirements and tests applicable to all types of miniature fuse-links (e.g. cartridge fuse-links, sub-miniature fuse-links, universal modular fuse-links and miniature fuse-links for special applications) for the protection of electric appliances, electronic equipment and component parts thereof normally intended to be used indoors. This document does not apply to fuses intended for the protection of low-voltage electrical installations. These are covered by IEC 60269, Low Voltage Fuses. Specific details covering each major subdivision are given in subsequent parts. This document does not apply to fuses for appliances intended to be used under special conditions, such as in a corrosive or explosive atmosphere.
The object of this document is
- to establish uniform requirements for miniature fuses so as to protect appliances or parts of appliances in the most suitable way,
- to define the performance of the fuses, so as to give guidance to designers of electrical appliances and electronic equipment and to ensure replacement of fuse-links by those of similar dimensions and characteristics,
- to define methods of testing,
- to define maximum sustained dissipation of fuse-links to ensure good compatibility of stated power acceptance when used with fuse-holders according to this document (see IEC 60127-6).
Coupe-circuits miniatures - Partie 1: Définitions pour coupe-circuits miniatures et exigences générales pour éléments de remplacement miniatures
IEC 60127-1:2023 est disponible sous forme de IEC 60127-1:2023 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L’IEC 60127-1:2023 couvre les exigences générales et les essais applicables à tous les types d’éléments de remplacement miniatures (par exemple, éléments de remplacement à cartouches, éléments de remplacement subminiatures, éléments de remplacement modulaires universels et éléments de remplacement miniatures pour applications spéciales) employés pour la protection des appareils électriques, du matériel électronique et de leurs constituants, normalement destinés à être utilisés à l'intérieur. Le présent document ne s'applique pas aux coupe-circuits destinés à la protection des installations électriques à basse tension. Ces derniers sont couverts par l'IEC 60269, Fusibles basse tension. Des informations détaillées spécifiques concernant chaque subdivision principale sont indiquées dans les parties subséquentes. Le présent document ne s’applique pas aux coupe-circuits placés dans des appareils destinés à être utilisés dans des conditions particulières, telles qu’une atmosphère corrosive ou explosive.
Le présent document a pour objet
- d’établir des exigences uniformes pour les coupe-circuits miniatures de manière à assurer la protection des appareils ou des parties d'appareils de la façon la plus appropriée;
- de définir les caractéristiques des coupe-circuits de manière à fournir des recommandations aux concepteurs d'appareils électriques et de matériel électronique, et à assurer le remplacement des éléments de remplacement par - d'autres de dimensions et de caractéristiques identiques;
- de définir des méthodes d'essai;
- de définir la puissance dissipée maximale des éléments de remplacement pour assurer une bonne compatibilité de la puissance admissible indiquée avec celle des ensembles-porteurs selon le présent document (voir l’IEC 60127-6).

MINIATURE FUSES –
Part 1: Definitions for miniature fuses and
general requirements for miniature fuse-links
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 s
