IEC 62423:2007

Type B residual current operated circuit-breakers with and without integral overcurrent protection for household and similar uses (Type B RCCBs and Type B RCBOs)

The scope of IEC 61008-1 and IEC 61009-1 applies. This standard specifies requirements and tests for type B RCDs. Requirements and tests given in this standard are in addition to the requirements of type A residual current devices. 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 in case of three phase supply.

Interrupteurs automatiques à courant différentiel résiduel de Type B avec et sans protection contre les surintensités incorporée pour usages domestiques et analogues (ID et DD de Type B)

Les domaines d'application de la CEI 61008-1 et de la CEI 61009-1 s'appliquent. La présente norme spécifie les exigences et les essais pour les DDR de Type B. Les exigences et les essais donnés dans la présente norme complètent les exigences des dispositifs à courant différentiel résiduel de Type A. Les ID de Type B et les DD de Type B sont aptes à assurer la protection en cas de courants différentiels alternatifs sinusoïdaux jusqu'à 1 000 Hz, de courants différentiels continus pulsés et de courants différentiels continus lissés dans le cas d'une alimentation triphasée.

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 acc
