IEC 62423:2009/COR1:2011

IEC 62423:2009/COR1:2011 is a corrigendum to the parent document IEC 62423:2009, providing a targeted correction for the requirements covering type F and type B residual current operated circuit-breakers with and without integral overcurrent protection for household and similar uses. For engineering, testing, and procurement teams, this supporting document matters because it helps ensure that technical review and compliance workflows are based on the corrected reference. It is especially relevant where safety verification, documented evaluation, and conformity assessment depend on accurate interpretation of the parent specification.

What is IEC 62423:2009/COR1:2011?

IEC 62423:2009/COR1:2011 is a corrigendum linked to IEC 62423:2009, so it should be used as a modifying reference rather than a standalone technical document. Its role is to correct or clarify the original requirements for type F and type B residual current operated circuit-breakers, including versions with and without integral overcurrent protection. In practice, it supports technical validation, specification control, and compliance preparation by helping users rely on the most accurate version of the source material during engineering documentation and test planning.

Applications of IEC 62423:2009/COR1:2011

This corrigendum is typically used in product evaluation, laboratory evaluation, and procurement review for protective devices intended for household and similar electrical installations. It can be useful where residual current protection, operational consistency, and safety documentation are part of the technical assessment for low-voltage equipment. Teams involved in certification, QA review, or regulatory preparation may consult IEC 62423:2009/COR1:2011 when checking that test plans, design records, and conformity assessment files align with the corrected parent reference.

Why is IEC 62423:2009/COR1:2011 important?

Accurate supporting references are important in electrical safety work because even small corrections can affect testing consistency, engineering validation, and documented compliance decisions. IEC 62423:2009/COR1:2011 helps reduce interpretation risk when evaluating residual current operated circuit-breakers against the parent requirements, especially in quality workflows where traceable documentation is expected. For organizations managing procurement or conformity assessment, using the corrigendum supports more reliable technical assessment and lowers the chance of basing decisions on outdated text.
