Residual current devices with or without overcurrent protection for socket-outlets for household and similar uses (IEC 62640:2011, modified); German version HD 62640:2015
Fehlerstrom-/Differenzstrom-Schutzeinrichtung mit oder ohne Überstromschutz für Steckdosen für Hausinstallationen und für ähnliche Anwendungen (IEC 62640:2011, modifiziert); Deutsche Fassung HD 62640:2015
Overview
This International Standard applies to residual current-operated devices (RCD) incorporated in, or specially intended for use with two pole socket-outlets, with or without earthing contact for household and similar uses (SRCD: socket-outlet residual current device). SRCDs, according to this standard, are intended to be used in single phase systems such as phase to neutral or phase to phase or phase to earthed middle conductor. SRCDs are only intended to provide additional protection for downstream circuits. SRCDs are intended for use in circuits in which fault protection (indirect contact protection) has already been ensured upstream of the SRCD. The responsible committee is Subcommittee DKE/UK 541.3 "Fehlerstrom-Schutzeinrichtungen" ("Residual current devices") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
