Miniature fuses - Part 6: Fuse-holders for miniature fuse-links

IEC 60127-6:2014 is applicable to fuse-holders for miniature cartridge fuse-links according to IEC 60127-2 and sub-miniature fuse-links according to IEC 60127-3 for the protection of electric appliances, electronic equipment and component parts thereof, normally intended for use indoors. Examples of fuse-holder types with different features are given. This part of IEC 60127 applies to fuse-holders with: - a maximum rated current of 16 A; and - a maximum rated voltage of 1 500 V d.c. or 1 000 V a.c.; and - for use up to 2 000 m above sea-level, unless otherwise specified. The object of this standard is to establish uniform requirements for safety and the assessment of electrical, mechanical, thermal and climatic properties of fuse-holders and the compatibility between fuse-holders and fuse-links. This second edition cancels and replaces the first edition published in 1994, its Amendment 1 (1996) and Amendment 2 (2002). This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - modify the arrangement of the fuse-holder samples in the planes in 13.1.1; - add a new test 13.2.2: Glow-wire ignition test; - change maximum gauge size for standard sheets 3 and 4 from 0,70 to 0,63 in table 5; - change minimum gauge size for standard sheets 3 and 4 from 0,55 to 0,56 in table 5. Keywords: fuse-holders for miniature cartridge fuse-links, sub-miniature fuse-links, protection of electric appliances, electronic equipment and component parts.

Coupe-circuits miniatures - Partie 6: Ensembles-porteurs pour cartouches de coupe-circuits miniatures

L'IEC 60127-6:2014 s'applique aux ensembles-porteurs pour éléments de remplacement à cartouches conformes à l'IEC 60127-2 et aux éléments de remplacement subminiatures conformes à l'IEC 60127-3 pour la protection d'appareils électriques, de matériels électroniques et de leurs éléments constituants, normalement destinés à être utilisés à l'intérieur de bâtiments. Des exemples de types d'ensembles-porteurs dont les caractéristiques sont différentes sont indiqués. La présente partie de l'IEC 60127 s'applique: - aux ensembles-porteurs de courant assigné maximal de 16 A; et - de tension assignée maximale de 1 500 V c.c. ou 1 000 V c.a.; - et pour l'utilisation jusqu'à 2 000 m au-dessus du niveau de la mer, sauf spécification contraire. La présente norme a pour objet d'établir des exigences uniformes relatives à la sécurité et à l'évaluation des propriétés électriques, mécaniques, thermiques et climatiques des ensembles-porteurs et à la compatibilité entre l'ensemble-porteur et l'élément de remplacement. Cette deuxième édition annule et remplace la première édition parue en 1994, son Amendement 1 (1996) et son Amendement 2 (2002). Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - modification de la disposition des échantillons d'ensembles-porteurs dans les plans en 13.1.1; - ajout d'un nouvel essai 13.2.2: Essai d'allumabilité au fil incandescent; - modification de la taille maximale des calibres pour les feuilles de norme 3 et 4 de 0,70 à 0,63 au Tableau 5; - modification de la taille minimale des calibres pour les feuilles de norme 3 et 4 de 0,55 à 0,56 au Tableau 5. Mots clés: ensembles-porteurs pour éléments de remplacement à cartouches, éléments de remplacement subminiatures, protection d'appareils électriques, de matériels électroniques et de leurs éléments constituants

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 pos
