IEC 62271-110:2023 is available as IEC 62271-110:2023 RLV<\/span> which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 62271-110:2023 is applicable to AC switching devices designed for indoor or outdoor installation, for operation at frequencies of 50 Hz and 60 Hz on systems having voltages above 1 000 V and applied for inductive current switching. It is applicable to switching devices (including circuit-breakers in accordance with IEC 62271-100) that are used to switch high?voltage motor currents and shunt reactor currents and also to high-voltage contactors used to switch high-voltage motor currents as covered by IEC 62271-106. This fifth edition cancels and replaces the fourth edition published in 2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: references to IEC 62271-100 and IEC 62271-106 have been updated to the latest editions.<\/p>\n
