IEC 60947-3:1990/COR1:1991 Corrigendum 1 — Low-voltage switchgear and controlgear. Part 3: Switches, disconnectors, switch-disconnectors and fuse-combination units
This document serves as a corrigendum for the foundational specification concerning low-voltage switchgear and controlgear. It addresses specific clauses related to switches, isolators, and switch-fuse combination assemblies within the third part of the broader series. The content provides official corrections to technical requirements and test procedures originally established in the previous edition. By detailing these amendments, the text ensures that the intended performance criteria and safety margins are accurately maintained across various international applications. It clarifies ambiguities found in the main standard and updates specific parameter definitions to reflect current engineering consensus. This adjustment is essential for manufacturers and testing laboratories to maintain consistency in product evaluation. The document is designed to be integrated directly with the primary technical specification, ensuring that all subsequent interpretations and compliance assessments rely on the corrected information. It represents a formal update to the technical framework without altering the overall scope of the original standard.
