Electrical accessories - Circuit-breakers for overcurrent protection for household and similar installations - Part 1: Circuit-breakers for a.c. operation
IEC 60898-1:2015 applies to a.c. air-break circuit-breakers for operation at 50 Hz, 60 Hz or 50/60 Hz, having a rated voltage not exceeding 440 V (between phases), a rated current not exceeding 125 A and a rated short-circuit capacity not exceeding 25 000 A. This second edition cancels and replaces the first edition published in 2002, Amendment 1:2002 and Amendment 2:2003. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) Revision of 9.5 Terminals
b) Revision of the test of glow wire
c) Simplification of the figures for short circuit tests.
The contents of the corrigendum of November 2015 have been included in this copy. This bilingual version (2016-11) corresponds to the English version, published in 2015-03. The French version of this standard has not been voted upon.
Petit appareillage électrique - Disjoncteurs pour la protection contre les surintensités pour installations domestiques et analogues - Partie 1: Disjoncteurs pour le fonctionnement en courant alternatif
L'IEC 60898-1:2015 s'applique aux disjoncteurs à coupure dans l'air pour courant alternatif à 50 Hz, 60 Hz ou 50/60 Hz, ayant une tension assignée ne dépassant pas 440 V (entre phases), un courant assigné ne dépassant pas 125 A et un pouvoir de coupure assigné ne dépassant pas 25 000 A. Cette deuxième édition annule et remplace la première édition publiée en 2002, Amendement 1:2002 et Amendement 2:2003. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) Révision de 9.5 Bornes
b) Révision de l'essai au fil incandescent
c) Simplification des figures pour les essais de court-circuit.
Le contenu du corrigendum de novembre 2015 a été inclus dans cet exemplaire. La présente version bilingue (2016-11) correspond à la version anglaise monolingue publiée en 2015-03. La version française n'a pas été soumise au vote.
