HD 62640:2015

Residual current devices with or without overcurrent protection for socket-outlets for household and similar uses

IEC 62640:2011 applies to residual current-operated devices (RCD) incorporated in, or specifically intended for use with two pole socket-outlets, with or without earthing contact for household and similar uses (SRCD: socket-outlet residual current devices). 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 downstream of the SRCD. SRCDs are intended for use in circuits where the fault protection (indirect contact protection) is already assured upstream of the SRCD.

Dispositifs à courant différentiel résiduel avec ou sans protection contre les surintensités pour les socles de prises de courant destinés à des installations domestiques et analogues

La CEI 62640:2011 s'applique aux dispositifs à courant différentiel résiduel (DDR) incorporés, ou destinés tout particulièrement à une utilisation avec des socles de prises de courant bipolaires avec ou sans contact à la terre pour des installations domestiques et analogues (DDRPC: dispositif à courant différentiel résiduel pour les socles de prises de courant). Les DDRPC, conformes à la présente norme, sont destinés à être utilisés dans les systèmes monophasés tels que phase et neutre ou phase-phase ou entre phase et conducteur milieu mis à la terre. Les DDRPC sont destinés uniquement à assurer une protection supplémentaire en aval du DDRPC. Les DDRPC sont destinés à être utilisés dans les circuits où la protection en cas de défaut (protection contre le contact indirect) est déjà assurée en amont du DDRPC.

Naprave na preostali (diferenčni) tok z nadtokovno zaščito ali brez nje za vtičnice za gospodinjsko in podobno rabo

Standard IEC 62640:2011 se uporablja za naprave na preostali (diferenčni) tok (RCD), ki so vgrajene v vtičnice z ozemljitvenim priključkom za gospodinjsko in podobno rabo (SRCD: naprave na preostali (diferenčni) tok za vtičnice) ali so namenjene izključno za uporabo z njimi. V skladu s tem standardom so naprave na preostali (diferenčni) tok za vtičnice namenjene za uporabo v enofaznih sistemih, kot je napajanje med faznim in nevtralnim, med faznim in faznim ali med faznim in ozemljenim srednjim vodnikom. Naprave na preostali (diferenčni) tok za vtičnice so namenjene za zagotavljanje dodatne zaščite le od teh naprav naprej. Naprave na preostali (diferenčni) tok za vtičnice so namenjene za uporabo v tokokrogih, kjer je okvarna zaščita (zaščita pred neposrednim dotikom) že zagotovljena pred temi napravami.

Overview

HD 62640:2015 (CLC endorsement of IEC 62640:2011, modified) covers residual current devices (RCDs) incorporated in, or specifically intended for use with, two‑pole socket‑outlets for household and similar uses - so‑called SRCDs (socket‑outlet residual current devices). The harmonization document is intended for single‑phase systems (phase‑to‑neutral or phase‑to‑phase) and defines requirements where SRCDs provide supplementary protection downstream, assuming fault protection is already provided upstream. HD 62640:2015 is a CENELEC document that supports EU directives (including the LVD).

Key topics and requirements

• Scope and classification: Specifies that SRCDs are only for supplementary protection in household and similar socket‑outlet applications and clarifies system types covered.
• Rated values: Aligns preferred values with European practice - rated voltage 230 V and preferred frequency 50 Hz (per IEC 60038 reference).
• Characteristics: Defines expected electrical and functional characteristics of SRCDs used with socket‑outlets (sensitivity classes, operational behavior).
• Construction and marking: Requirements for mechanical and electrical construction, clear product marking and information relevant to installation and safe operation.
• Testing and verification: Detailed test requirements for electrical trip behaviour, mechanical endurance, and response under supply‑failure conditions. The harmonized text includes specific test procedures and performance verification (trip performance and operation timing are covered).
• Conformance and national requirements: Where IEC references relate to socket‑outlet design (e.g., IEC 60884‑1), the harmonized document defers to the national requirements of the country where the product is placed on the market.

Applications and who uses this standard

• Manufacturers of RCDs and combined RCD/overcurrent devices designed for socket‑outlets in homes, hotels, offices, caravans and similar premises.
• Product designers and compliance engineers ensuring SRCD designs meet European harmonized technical requirements.
• Test laboratories and certification bodies performing type testing and verification against HD 62640:2015 requirements.
• Regulators and procurement specialists verifying conformity with EU directives and national regulations for household electrical accessories.
• Electrical installers and specifiers consulting the standard for safe application and correct selection of SRCDs within downstream circuits.

Related standards

• IEC 62640:2011 (original international standard)
• IEC 60038 (rated voltages)
• IEC 61439‑3 (reference for certain equipment exclusions)
• National socket‑outlet standards (used where IEC 60884‑1 references are replaced by national requirements)
