Portable residual current devices without integral overcurrent protection for household and similar use (PRCDs) (IEC 61540:2023)
This document applies to portable residual current devices (PRCDs) for household and similar uses, consisting of a plug, a residual current device (RCD) and one or more socket-outlets or a provision for connection. They do not incorporate overcurrent protection. They are intended for single- and two-phase systems for rated currents not exceeding 16 A for rated voltages not exceeding 250 V AC, or for rated current not exceeding 32 A for rated voltages not exceeding 130 V AC to earth. They are intended to provide protection against shock hazard in case of direct contact, in addition to the protection provided by the fixed installations for the circuit downstream.
PRCDs have a rated residual operating current not exceeding 0,03 A.
The plug and socket-outlet parts of a PRCD are covered by the national standard of the country where the PRCD is placed on the market. If no national requirements exist, IEC 60884 1 is used.
This document applies to portable devices performing simultaneously the functions of detection of the residual current, of comparison of the value of this current with the residual operating value and of opening of the protected circuit when the residual current exceeds this value.
PRCDs providing an additional function of detecting faults on the supply side with a defined behaviour in case of supply failures or miswiring (PRCD-S) are also covered by this document.
PRCDs are not intended to be used as parts of fixed installations. Their connecting means can be plugs, socket-outlets, terminals or cords.
NOTE 1 The requirements for PRCDs are in compliance with the general requirements of IEC 60755. PRCDs are essentially intended to be operated by ordinary persons and designed not to require maintenance.
NOTE 2 An integral fuse is used, if necessary, for the relevant plug and socket-outlet system.
The switching contacts of the PRCDs are not intended to provide isolation, as isolation can be ensured by disconnecting the plug.
The requirements of this document apply for environmental conditions as defined in 7.1. Additional requirements can be necessary for PRCDs used in locations having more severe environmental conditions.
PRCDs including batteries are not covered by this document.
This document does not contain additional requirements for PRCDs without earthing contacts for which specific requirements can apply. This document can, however, be used as a guide for such devices which are intended to be used with Class II appliances only.

Dispositifs différentiels portables à courant résiduel (PCDM) sans protection incorporée contre les surintensités pour usages domestiques et analogues (IEC 61540:2023)
L'IEC 61540:2023 s'applique aux dispositifs différentiels portables à courant résiduel (PCDM) pour usages domestiques et analogues, qui comportent une fiche de prise de courant, un dispositif à courant différentiel résiduel (DDR), ainsi qu'un ou plusieurs socles de prises de courant ou un moyen de connexion. Ces dispositifs n'incorporent pas de protection contre les surintensités. Ils sont destinés à des systèmes monophasés et diphasés pour des courants assignés inférieurs à 16 A à des tensions assignées ne dépassant pas 250 V en courant alternatif, ou pour des courants assignés inférieurs à 32 A à des tensions assignées ne dépassant pas 130 V en courant alternatif à la terre. Ils sont destinés à procurer une protection contre le danger de choc électrique en cas de contact direct en complément à la protection procurée par les installations fixes situées en aval du circuit.
Cette deuxième édition annule et remplace la première édition parue en 1997 et son Amendement 1:1998. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) le contenu du présent document a été révisé et aligné sur l'IEC 60755 (publication groupée de sécurité relative aux dispositifs à courant différentiel résiduel) et sur la bibliothèque de normes "blocs et modules";
b) la classification "4.3 Selon le comportement après ouverture automatique en cas de défaillance de la tension d'alimentation" a été ajoutée;
c) de nouvelles exigences et de nouveaux essais ont été ajoutés afin de couvrir la fonction de protection contre le danger de choc électrique mise en œuvre:
- vérification du fonctionnement correct en cas d'absence du conducteur de protection;
- vérification du fonctionnement correct en cas de conducteur de protection actif et donc dangereux;
- vérification du fonctionnement correct en cas de perte du conducteur de protection;
- vérification du comportement en cas de courant de défaut externe dans le conducteur de protection;
d) les distances d'isolement dans l'air et les lignes de fuite ont été révisées et alignées sur l'IEC 62752 (IC-CPD);
e) les valeurs des tensions minimales de fonctionnement ont été révisées;
f) des exigences et un essai ont été ajoutés pour la température de l'air ambiant comprise entre –25 °C et +40 °C;
g) l'essai des propriétés diélectriques a été révisé et aligné sur la bibliothèque de normes "blocs et modules";
h) les articles concernés ont été alignés sur l'IEC 62752 (IC-CPD); l'IC-CPD est une norme de produit qui décrit des produits/fonctions analogues;
i) toutes les annexes ont été révisées et adaptées au contenu du document principal.
