About This Item
IEC 60947-3:2020/COR1:2021 is a corrigendum linked to the low-voltage switchgear and controlgear series, supporting the technical record for switches, disconnectors, switch-disconnectors and fuse-combination units. For engineering, procurement, and compliance teams, it matters because even a corrective document can affect how a technical document is interpreted, reviewed, and applied in documented evaluation and conformity assessment workflows. IEC 60947-3:2020/COR1:2021 should be used together with its parent reference to support accurate technical review and operational consistency.
What is IEC 60947-3:2020/COR1:2021?
This corrigendum is a supporting document associated with IEC 60947-3:2020, which covers low-voltage switchgear and controlgear for switching, isolation, and fused switching functions. As a correction notice, IEC 60947-3:2020/COR1:2021 is intended to modify or clarify the parent text rather than act as a standalone engineering specification. It is relevant when teams are checking technical compliance, aligning verification activities, or maintaining controlled documentation for product evaluation and regulatory preparation.
Applications of IEC 60947-3:2020/COR1:2021
Organizations may consult this corrigendum when reviewing product files for low-voltage switching equipment used in panels, distribution assemblies, industrial control systems, and related electrical equipment. It can support technical assessment during design confirmation, laboratory evaluation, and certification-oriented testing workflows where the parent document is already in use. Procurement and quality teams may also rely on it to confirm that referenced requirements remain aligned across specifications, test plans, and engineering documentation.
Why is IEC 60947-3:2020/COR1:2021 important?
Corrective documents help reduce ambiguity in technical compliance work, especially where switching devices must meet clearly defined safety and performance expectations. By pairing the corrigendum with the parent reference, organizations can strengthen conformity assessment preparation, avoid documentation drift, and improve consistency across verification activities. IEC 60947-3:2020/COR1:2021 is therefore useful for risk management, technical validation, and procurement decisions that depend on a controlled and accurate compliance reference.
