IEC/SC 23E - Circuit-breakers and similar equipment for household use
To prepare and to update standards for: - circuit-breakers and residual current devices of rated currents not exceeding 125 A and rated voltages not exceeding 440 V for protection against overcurrent and/or against electric shock in domestic and similar installations, - residual current devices for monitoring the conditions of insulation of domestic and similar installations, - circuit-breakers for equipment of rated currents not exceeding 125 A and rated voltages not exceeding 440 V designed to protect equipment for use in domestic and similar installations, - electromechanical contactors for household and similar purposes, - control and protection devices for battery-powered vehicle supplies, - arc fault detection devices (AFDD) of rated currents not exceeding 63 A and rated voltages not exceeding 240 V a.c. for household and similar uses. The standards concern devices intended to be used by ordinary persons in installations or equipment not subject to maintenance and contain all specifications necessary for certification purposes: sets of samples to be submitted, test sequences to be applied and conditions for approval. They shall also include all specifications necessary for certification purposes concerning the groups of samples, the tests sequences each group shall be submitted and the number of failures admitted. In working out such standards and according to the guidelines given by the SMB, close coordination is being kept continuously with SC 121A, dealing with the standards for low voltage switchgear and controlgear mainly intended to be used by instructed persons in installations subject to supervision and maintenance (In particular SC 121A is the leader for the preparation of standards for circuit breaker, whilst SC 23E is the leader for the preparation of standards for RCDs). The work of the subcommittees takes into account the specifications prepared by TC 109, SC 77A and by TC 64. An official liaison with CTL has been established by nominating a liaison member who is also member of the parallel WG in the CTL organization SC 23E has Group Safety Function for: Residual Current Devices (RCDs) Definition of Residual Current Devices taken from IEC 60755 a residual current device is a mechanical switching device designed to make, carry and break currents under normal service conditions and to cause the opening of the contacts when the residual current attains a given value under specified conditions
Disjoncteurs et appareillage similaire pour usage domestique
Préparer et mettre à jour les normes pour: - disjoncteurs et dispositifs de protection à courant différentiel résiduel prévus pour des courants assignés n'excédant pas 125A et des tensions assignées n'excédant pas 440V pour la protection contre les surintensités et/ou contre les chocs électriques dans des installations domestiques et similaires, - contrôleurs d’isolement à courant différentiel résiduel pour installations domestiques et similaires, - disjoncteurs pour équipements prévus pour des courants assignés n'excédant pas 125 A et des tensions assignées n'excédant pas 440 V conçues pour protéger des équipements utilisés dans des installations domestiques et similaires, - contacteurs électromécaniques à usages domestiques et similaires, - appareil de contrôle et de protection pour la charge des véhicules électriques, - dispositifs pour la détection de défaut d’arcs (DPDA) prévus pour des courants assignés n'excédant pas 125A et des tensions assignées n'excédant pas 440 V pour les utilisations domestiques et similaires. - guide pour les fonctions additionnelles associées aux dispositifs de protection - dispositifs à refermeture automatique - dispositifs de protection contre les surtensions à fréquence industrielle Ces normes intéressent les dispositifs destinés à être utilisés par des personnes non averties ni qualifiées dans des installations ou équipements qui ne sont pas entretenus ; elles contiennent toutes les spécifications nécessaires aux fins de la certification : jeu d’échantillons à fournir, séquences d'essais à appliquer et conditions d'acceptation. Elles contiendront également toutes les spécifications nécessaires à des fins de certification en ce qui concerne les groupes d’échantillons, les séquences d’essais appliquées à chaque groupe et le nombre d’échecs admis. Dans le cadre de ces normes et selon les directives données par le SMB, une coordination étroite est continuellement maintenue avec le SC 121A, en ce qui concerne les normes d'appareillage de basse tension principalement destinées à être utilisées par des personnes averties dans des installations soumises à une supervision et à de la maintenance (plus particulièrement, le SC 121A est le leader pour la préparation des normes pour le disjoncteur, tandis que le SC 23E est le leader pour la préparation des normes pour les DDR). Les travaux des sous-comités prennent en compte les spécifications préparées par les TC 109, SC 77A et TC 64. Une liaison officielle avec CTL a été établie en nommant un membre de liaison qui est aussi membre du groupe de travail correspondant dans l’organisation du CTL. Le SC 23E a une fonction horizontale de sécurité pour les Dispositifs à Courant Différentiel Résiduel (DDR). Définition des Dispositifs à Courant Différentiel Résiduel d’après l’IEC 60755 : dispositif mécanique de coupure destiné à établir, supporter et couper des courants dans les conditions de service normales et à provoquer l'ouverture des contacts quand le courant différentiel atteint, dans des conditions spécifiées, une valeur donnée.

The International Organization for Standardization (ISO) is an independent, non-governmental international organization that develops and publishes international standards. Founded in 1947 and headquartered in Geneva, Switzerland, ISO brings together experts from 170+ member countries to share knowledge and develop voluntary, consensus-based standards that support innovation and provide solutions to global challenges.
A Subcommittee (SC) in ISO operates under a Technical Committee and focuses on a specific subset of the TC's scope. Subcommittees develop standards and technical specifications in their specialized area, reporting to their parent Technical Committee. They may also have working groups for detailed technical work.
