IEC 62271-111:2012(E) applies to all overhead, pad mounted, dry vault and submersible single or multi-pole alternating current automatic circuit reclosers and fault interrupters for rated maximum voltages above 1 000 V and up to 38 kV. This second edition cancels and replaces the first edition, published in 2005, and constitutes a technical revision. The main changes with respect to the previous edition are as follows:
a) addition of exclusion of devices with dependent manual operation to 1.1;
b) harmonization of the amplitude factor kaf used for calculating the TRV for cable connected systems consistent with recent harmonization of the circuit-breaker standards between IEEE and IEC;
c) deletion of requirements for radio influence voltage (RIV) tests;
d) addition of specifications and ratings to cover the cutout recloser and its special requirements.
This standard has been jointly revised by Switchgear Committee of the IEEE Power and Energy Society, in cooperation with subcommittee 17A: High-voltage switchgear and controlgear with reference to IEEE Std C37.60-2012(E).

This publication is to be read in conjunction with IEC 62271-1:2007.
