IEC 63052:2019

Power frequency overvoltage protective devices (POPs) for household and similar applications

IEC 63052:2019 applies to devices for power frequency overvoltage protection (hereafter referred to as "POP") for household and similar uses, with a rated frequency of 50 Hz, 60 Hz or 50/60 Hz, with rated voltage not exceeding 230 V AC (between phase and neutral), and with rated current not exceeding 63 A, either consisting of a functional unit in combination with a main protective device (MPD), or as one single device having opening means able to open the protected circuit in specified conditions.
The main protective device is a circuit-breaker, an RCCB or an RCBO.
The contents of the corrigendum of November 2019 have been included in this copy.

Dispositifs de protection contre les surtensions à fréquence industrielle (POP) pour les applications domestiques et similaires

L'IEC 63052:2019 s'applique aux dispositifs de protection contre les surtensions à fréquence industrielle (appelés ici "dispositifs POP" - Power frequency Overvoltage Protection) pour les appareils domestiques et similaires, avec une fréquence assignée de 50 Hz, 60 Hz ou 50 Hz/60 Hz, une tension assignée maximale de 230 V en courant alternatif (entre phase et neutre) et un courant assigné maximal de 63 A, composés d'une unité fonctionnelle combinée à un dispositif de protection principal (MPD) ou se présentant sous la forme d'un dispositif unique équipé d'un système d'ouverture permettant d'ouvrir le circuit protégé dans les conditions spécifiées.
Le dispositif de protection principal est un disjoncteur, un interrupteur différentiel sans protection incorporée contre les surintensités (ID) ou un disjoncteur différentiel résiduel avec protection incorporée contre les surintensités (DD).
Le contenu du corrigendum de novembre 2019 a été pris en considération dans cet exemplaire.
