DIN EN IEC 62271-110 VDE 0671-110:2018-08

This part of IEC 62271 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 highvoltage motor currents as covered by IEC 62271-106. Switching unloaded transformers, i.e. breaking transformer magnetizing current, is not considered in this document.
