Low-voltage switchgear and controlgear. Part 6: Multiple function equipment — Section One: Automatic transfer switching equipment

This document represents a corrigendum addressing an earlier version of the specification concerning low-voltage switchgear and controlgear. Specifically, it focuses on the subset of devices designed for multi-functional operations, with a dedicated section on automatic transfer equipment. The amendment serves to correct errors or omissions found in the original technical content issued several years prior to its formalization. These updates ensure that the definitions, testing procedures, and operational requirements for automatic transfer switches remain accurate and safe for international application. By incorporating these corrections, the technical documentation maintains consistency with current safety expectations and engineering practices within the global electrical industry. The scope covers the design, construction, and performance criteria essential for equipment that switches between power sources automatically. This amendment acts as a formal revision, reinforcing the integrity of the standard without altering its fundamental structure or intended purpose. It is an integral part of the broader framework governing low-voltage control systems, ensuring reliability in critical power distribution scenarios.
