Overview

SIST EN 62423:2013/A11:2021 is a European standard developed by CLC/TC 23E that specifies requirements for Type F and Type B residual current operated circuit-breakers (RCCBs). These devices can include integral overcurrent protection or operate without it, intended primarily for household and similar electrical installations. This amendment to EN 62423:2012 was approved in March 2021 and reflects updated testing procedures and electromagnetic compatibility (EMC) requirements.

This standard supports compliance with relevant EU Directives, including Electromagnetic Compatibility Directive 2014/30/EU and the Low Voltage Directive 2014/35/EU, positioning it as a key document for manufacturers and certification bodies engaged in the production, verification, and installation of RCCBs designed for residential and analogous environments.

Key Topics

• Residual Current Circuit-Breakers Types F and B
  Type F and Type B RCCBs provide leak current detection including smooth direct current components, rendering them suitable for advanced protection scenarios in household power systems.

• Overcurrent Protection Integration
  The standard covers RCCBs with or without integral overcurrent protective elements, allowing flexibility in device configuration depending on specific electrical system requirements.

• Testing and Verification Methods
  The amendment revises test sequences, including:

  • Verification of RCCB tripping performance with smooth direct current at 2.5 times rated residual current.
  • Enhanced Electromagnetic Compatibility (EMC) testing aligned with EN 61543 and CISPR 14-1 standards to ensure robust device performance under electromagnetic disturbances.
  • Updated sample testing procedures for conformity assessment, specifically for Type B RCCBs and RCBOs (Residual Current Breaker with Overcurrent Protection).

• Harmonization with International Standards
  EN 62423 includes references and incorporates modifications to harmonize with IEC standards and other European standards such as EN 61008 and EN 61009 series, and the EMC standard EN 61543.

• Conformity and Certification Guidelines
  Clarifies verification approaches by manufacturers and independent bodies, standardizing terminology and compliance pathways under ISO/IEC Guides.

Applications

• Household Electrical Safety
  This standard applies directly to circuit-breakers used in residential installations, enhancing protection from electric shocks caused by residual currents, including those with smooth DC leakage.

• Similar Uses Beyond Households
  Devices covered by EN 62423 are suitable for comparable environments such as office buildings, small commercial premises, and light industrial installations where similar electrical safety requirements exist.

• Integration into Electrical Distribution Systems
  Ensures RCCBs conform to stringent detection and interruption criteria, making them reliable components for modern electrical distribution boards that require advanced protection against residual currents and overcurrent conditions.

• Guidance for Manufacturers and Testing Laboratories
  Provides test protocols and EMC requirements manufacturers must meet, enabling equipment certification for the EU market and facilitating smooth regulatory approvals.

Related Standards

• EN 61008 Series
  Covers RCCBs without integral overcurrent protection, referenced for comprehensive requirements complementing EN 62423.

• EN 61009 Series
  Pertains to combined residual current-operated circuit-breakers with integral overcurrent protection (RCBOs) and aligns with EN 62423 amendments.

• EN 61543
  Addresses electromagnetic compatibility for residual current devices, setting test criteria adopted in the latest EN 62423 revision.

• ISO/IEC Guides 2
  Provides terminology and guidance on conformity assessment referenced in verification processes.

• CISPR 14-1
  Emission limits related to household appliances and electrical equipment, including RCCBs, underpin EMC requirements in this standard.
