    Abstract - (Show below) - (Hide below)

    NEW!IEC 62271-110:2017 is available as IEC 62271-110:2017 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 62271-110:2017 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 fourth edition cancels and replaces the third edition published in 2012 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:

    - all switching devices are now covered, not only circuit-breakers;

    - a limited number of T10 tests no longer covers shunt-reactor switching tests below 52 kV;

    - evaluation and reporting of a re-ignition-free arcing time window has been added.
