IEC 62271-103:2021 is applicable to three-phase, alternating current switches and switch-disconnectors for their switching function, having making and breaking current ratings, for indoor and outdoor installations, for rated voltages above 1 kV up to and including 52 kV and for rated frequencies from 162/3 Hz up to and including 60 Hz. This document is also applicable to single-pole switches used on three-phase systems. This second edition cancels and replaces the first edition published in 2011. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:

- clarifications regarding the behaviour of the switch during breaking tests regarding current interruption and restrikes have been added;
- conditions of the switch after making and breaking tests have been clarified;
- a new informative Annex B intended to provide guidance for the calculation of Ief1 and Ief2 has been added;
- new rules for the combination of 50 Hz and 60 Hz switching tests have been defined and a new table (Table 7) has been added;
- tests with specified TRV have been modified to be in accordance with the practice described in IEC 62271-100;
- the behaviour of the switch during breaking tests has been clarified and boundaries for restrike allowance have been defined;
- explanations for short-circuit making tests have been added;
- vacuum integrity check after mechanical operations has been defined;
- all test voltages for single-phase capacitive testing have been grouped under 7.101.7.3.2 and have been confirmed by simulation and calculation.

Standard IEC 62271-103:2021 se uporablja za trifazna stikala za izmenični tok in ločilna stikala v zvezi z njihovo funkcijo preklapljanja, ki imajo nazivne vklopne in izklopne tokove ter so namenjena za namestitev v notranjih in zunanjih okoljih, za naznačene napetosti nad 1 kV do vključno 52 kV ter za nazivne frekvence od 162/3 Hz do vključno 60 Hz. Ta dokument se uporablja tudi za enopolna stikala v trifaznih sistemih. Druga izdaja razveljavlja in nadomešča prvo izdajo, objavljeno leta 2011. Ta izdaja je tehnično popravljena izdaja.
Ta izdaja v primerjavi s prejšnjo vključuje naslednje pomembne tehnične spremembe:
– ta dokument je bil usklajen s standardoma IEC 62271-1:2017 in IEC 62271-102:2018;
– dodana so bila pojasnila glede obnašanja stikala med preskusi izklopne zmogljivosti v zvezi s prekinitvijo toka in vnovičnim vklopom;
– pogoji za stikalo po preskusih vklopne in izklopne zmogljivosti so bili pojasnjeni;
– dodan je bil nov informativni dodatek B, ki podaja smernice za izračun vrednosti Ief1 in Ief2;
– opredeljena so bila nova pravila za kombinacijo preklopnih preskusov pri 50 Hz in 60 Hz ter dodana je bila nova preglednica (preglednica 7);
– preskusi s prehodno povratno napetostjo (TRV) so bili spremenjeni, da ustrezajo praksam iz standarda IEC 62271-100;
– obnašanje stikala med preskusi izklopne zmogljivosti je bilo pojasnjeno in opredeljene so bile meje za omogočanje vnovičnega vklopa;
– dodana so bila pojasnila za preskuse kratkostične vklopne zmogljivosti;
– opredeljen je bil vakuumski preskus po mehanskem delovanju;
– vse preskusne napetosti za enofazno kapacitivno preskušanje so bile razvrščene v točki 7.101.7.3.2 ter potrjene s simulacijo in izračunom.
