IEC 60947-6-2:2020/COR1:2021

IEC 60947-6-2:2020/COR1:2021 is a corrigendum to the published requirements for low-voltage switchgear and controlgear, specifically the part covering multiple function equipment and control and protective switching devices (or equipment) (CPS). As a supporting document to IEC 60947-6-2:2020, it is relevant when engineering teams, laboratories, and compliance groups need to align a technical file or verification record with the corrected text. In procurement and conformity assessment workflows, IEC 60947-6-2:2020/COR1:2021 helps ensure the governing reference is accurate before testing, specification review, or release decisions.

Overview of IEC 60947-6-2:2020/COR1:2021

This corrigendum is part of the IEC 60947 low-voltage switchgear and controlgear series and is tied directly to the parent document IEC 60947-6-2:2020. Its purpose is generally to correct or clarify the original publication rather than to act as a standalone technical rule set. For users involved in engineering documentation, technical review, or conformity assessment, the corrected wording may be important when interpreting requirements for control and protective switching devices or equipment. It supports consistent application of the parent standard in design, verification activities, and documented evaluation.

Compliance applications of IEC 60947-6-2:2020/COR1:2021

Organizations may use IEC 60947-6-2:2020/COR1:2021 when reviewing product specifications, preparing test plans, or checking that low-voltage control and protective switching equipment is assessed against the correct IEC text. It is particularly relevant for laboratories, certification teams, manufacturers, and procurement functions that depend on precise document control. In practical workflows, the corrigendum can help support technical validation, reduce ambiguity in quality workflows, and improve alignment between engineering documentation and compliance references during product evaluation or regulatory preparation.

Importance of compliance with IEC 60947-6-2:2020/COR1:2021

Using the corrigendum alongside the parent document helps reduce the risk of relying on outdated or incorrect clauses during design verification and testing workflows. That matters for safety, interoperability, and operational consistency in low-voltage switchgear and controlgear applications. For procurement and conformity assessment preparation, the corrected reference can improve confidence that technical acceptance criteria are based on the current published text. It also supports quality assurance by strengthening traceability across engineering specifications, test records, and compliance documentation.
