IEC 62423:2009/COR2:2021

IEC 62423:2009/COR2:2021 provides a corrigendum to the requirements for type F and type B residual current operated circuit-breakers with and without integral overcurrent protection for household and similar uses. IEC 62423:2009/COR2:2021 is relevant where engineering teams, procurement staff, and compliance reviewers need to work from the corrected technical text rather than the parent document alone. As a supporting document linked to IEC 62423:2009, it helps maintain consistency in technical review, documented evaluation, and conformity assessment workflows for low-voltage protection equipment.

Overview of IEC 62423:2009/COR2:2021

This corrigendum is a modifying reference that updates the parent publication rather than serving as a standalone product specification. It is associated with residual current operated circuit-breakers designed for household and similar applications, including type F and type B devices with or without integral overcurrent protection. For technical teams, IEC 62423:2009/COR2:2021 is useful when checking that design documentation, test plans, and compliance records reflect the corrected text. It supports more reliable technical validation and helps reduce ambiguity during review.

Compliance applications of IEC 62423:2009/COR2:2021

Organizations may use IEC 62423:2009/COR2:2021 during product evaluation, certification preparation, and laboratory evaluation of protective switching devices intended for household and similar electrical equipment. It is particularly relevant where residual current protection, operational consistency, and testing workflows must align with the parent standard and its correction. Procurement teams may also use it to verify that purchased documentation set references the current corrected requirement base, while engineering groups may use it to support risk management and technical assessment activities.

Importance of compliance with IEC 62423:2009/COR2:2021

Using the corrigendum alongside the parent document helps improve safety-focused compliance work by reducing the chance of relying on outdated wording. In practice, that can support more consistent testing, clearer engineering documentation, and better preparation for conformity assessment or regulatory review. For manufacturers and test laboratories, the corrected reference helps align technical requirements across design, verification activities, and quality workflows. For buyers and specifiers, it supports more dependable procurement decisions when comparing residual current protection devices for documented compliance.
