Full Description
IEC 62271-100:2008+A1:2012+A1:2017 is applicable to a.c. circuit-breakers designed for indoor or outdoor installation and for operation at frequencies of 50 Hz and 60 Hz on systems having voltages above 1 000 V. It is only applicable to three-pole circuit-breakers for use in three-phase systems and single-pole circuit-breakers for use in single-phase systems. This second edition cancels and replaces the first edition published in 2001 and its amendments 1 (2002) and 2 (2006). It also cancels and replaces IEC 61633 and IEC 62271-308. The main changes with respect to the previous edition are listed below:- the introduction of harmonised (IEC and IEEE) TRV waveshapes for rated voltages of 100 kV and above (amendment 1 to the first edition);
- the introduction of cable and line systems with their associated TRVs for rated voltages below 100 kV (amendment 2 to the first edition);
- the inclusion of IEC 61633 and IEC 62271-308.
This consolidated version consists of the second edition (2008), its amendment 1 (2012) and its amendment 2 (2017=. Therefore, no need to order amendments in addition to this publication.
This publication is to be read in conjunction with IEC 62271-1:2007. The contents of the corrigendum of December 2012 have been included in this copy.
