IEC 62271-100:2021/COR3:2024

IEC 62271-100:2021/COR3:2024 is a corrigendum linked to Corrigendum 3 - High-voltage switchgear and controlgear - Part 100: Alternating-current circuit-breakers, providing a supporting correction to the parent document IEC 62271-100:2021. For engineering, procurement, and compliance teams, it helps ensure that the technical reference used for high-voltage alternating-current circuit-breakers reflects the intended published text. In documentation control and technical review workflows, even a corrigendum can be important for maintaining consistency across specifications, test plans, and conformity assessment records.

Overview of IEC 62271-100:2021/COR3:2024

IEC 62271-100:2021/COR3:2024 should be read as a modifying reference rather than a standalone technical specification. Its scope is tied directly to the parent document covering high-voltage switchgear and controlgear, specifically alternating-current circuit-breakers. Organizations use corrigenda like this to align engineering documentation, verification activities, and compliance checks with the corrected published text. In practice, it supports more reliable technical validation by reducing the risk of working from an uncorrected edition during specification review, product evaluation, or laboratory assessment.

Compliance applications of IEC 62271-100:2021/COR3:2024

This corrigendum is relevant where teams maintain controlled copies of standards for circuit-breaker design, type testing, conformity assessment, or procurement review. It may be used alongside the parent reference in high-voltage equipment projects, internal quality workflows, and regulatory preparation activities that depend on accurate technical documentation. For laboratories and manufacturers, it can help preserve consistency between test instructions, product dossiers, and compliance references. IEC 62271-100:2021/COR3:2024 is therefore useful in environments where documented evaluation must match the corrected standard text.

Importance of compliance with IEC 62271-100:2021/COR3:2024

Using the corrected reference supports safety, operational consistency, and technical confidence in high-voltage circuit-breaker projects. In compliance-driven workflows, small textual corrections may affect how requirements are interpreted during engineering validation, testing, or procurement acceptance. IEC 62271-100:2021/COR3:2024 helps reduce ambiguity, improve traceability, and strengthen conformity assessment preparation by ensuring that teams work from the latest corrected version of the parent document. That matters for risk management, quality assurance, and dependable documentation control across the product lifecycle.
