(Main)General requirements for arc fault detection devices
General requirements for arc fault detection devices
IEC 62606:2013 applies to arc fault detection devices (AFDD) for household and similar uses in a.c. circuits. An AFDD is designed by the manufacturer:
- either as a single device having opening means able to open the protected circuit in specified conditions; or
- as a single device integrating a protective device; or
- as a separate unit, according to Annex D assembled on site with a declared protective device. The contents of the corrigendum of November 2013 have been included in this copy.
Exigences générales des dispositifs pour la détection de défaut d'arcs
La CEI 62606:2013 s'applique aux dispositifs pour la détection de défaut d'arc (DPDA) utilisés à des fins domestiques et analogues dans des circuits en courant alternatif (AC). Un DPDA est conçu par le constructeur:
- comme un dispositif unique doté d'un système d'ouverture pouvant ouvrir le circuit protégé dans les conditions spécifiées; ou
- comme un dispositif unique doté d'un dispositif de protection; ou
- comme une unité séparée, conformément à l'Annexe D, assemblée sur site avec un dispositif de protection déclaré. Le contenu du corrigendum de novembre 2013 a été pris en considération dans cet exemplaire.
