DESCRIPTION

IEC 62271-110:2017

IEC 62271-110:2017 is also 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. The contents of the corrigendum of December 2017 and of February 2018 have been included in this copy.
