IEC 62423:2009

Type F and type B residual current operated circuit-breakers with and without integral overcurrent protection for household and similar uses

The scope of IEC 61008-1 and IEC 61009-1 applies with the following additions. IEC 62423:2009 specifies requirements and tests for Type F and Type B RCDs (Residual Current Devices). Requirements and tests given in this standard are in addition to the requirements of Type A residual current devices. This standard can only be used together with IEC 61008-1 and IEC 61009-1. Type F RCCBs (Residual Current Circuit Breaker) and Type F RCBOs (Residual current Circuit Breaker with Overcurrent protection) with rated frequency 50 Hz or 60 Hz are intended for installations when frequency inverters are supplied between phase and neutral or phase and earthed middle conductor and are able to provide protection in case of alternating residual sinusoidal at the rated frequency, pulsating direct residual currents and composite residual currents that may occur. Type B RCCBs and Type B RCBOs are able to provide protection in case of alternating residual sinusoidal currents up to 1 000 Hz, pulsating direct residual currents and smooth direct residual currents. This second edition cancels and replaces the first edition published in 2007 and constitutes a technical revision. The main changes from the first edition are as follows:
- requirements and tests for Type F RCD have been introduced;
- requirements and test for two-pole Type B RCD have been introduced;
- new additional requirements and tests for Type B RCDs have been introduced to cover requirements for Type F too. The contents of the corrigendum 1 of December 2011 have been included in this copy and the corrigendum 2 of July 2021 applies to the French language only.

Interrupteurs automatiques à courant différentiel résiduel de type B et de type F avec et sans protection contre les surintensités incorporée pour usages domestiques et analogues

Les domaines d'application de la CEI 61008-1 et de la CEI 61009-1 s'appliquent avec les additions suivantes. La CEI 62423:2009 spécifie les exigences et les essais pour les DDR (dispositif de protection à courant différentiel résiduel) de Type B et de Type F. Les exigences et les essais donnés dans la présente norme complètent les exigences des dispositifs à courant différentiel résiduel de Type A. La présente norme ne peut être utilisée que conjointement à la CEI 61008-1 et à la CEI 61009-1. Les ID (interrupteur différentiel sans protection contre les surintensités incorporée) de Type F et les DD (interrupteur différentiel avec protection contre les surintensités incorporée) de Type F de fréquence assignée 50 Hz ou 60 Hz sont destinés à des installations dans lesquelles les convertisseurs de fréquence sont alimentés entre phase et neutre ou entre phase et conducteur milieu mis à la terre et sont aptes à assurer la protection en cas d'apparition de courant différentiel alternatif sinusoïdal à la fréquence assignée, de courant différentiel continu pulsé et de courant différentiel composé. Les ID de Type B et les DD de Type B sont aptes à assurer la protection en cas de courants différentiels résiduels alternatifs sinusoïdaux jusqu'à 1 000 Hz, de courants différentiels résiduels continus pulsés et de courants différentiels résiduels continus lissés. Cette deuxième édition annule et remplace la première édition publiée en 2007 dont elle constitue une révision technique. Les changements par rapport à la première édition sont les suivants:
- des exigences et essais ont été introduits pour le DDR de Type F;
- des exigences et essais ont été introduits pour le DDR à deux pôles de Type B;
- de nouvelles exigences et de nouveaux essais supplémentaires pour les DDR de Type B ont été introduits pour couvrir aussi les exigences et essais pour le Type F. Le contenu du corrigendum 1 de décembre 2011 et 2 de juillet 2021 a été pris en considération dans cet exemplaire.
