IEC 62271-102:2018+AMD1:2022 applies to alternating current disconnectors and earthing switches, designed for indoor and outdoor installations for nominal voltages above 1 000 V and for service frequencies up to and including 60 Hz. This second edition cancels and replaces the first edition published in 2001, Amendment 1:2011 and Amendment 2:2013. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:

b. clause numbering has been aligned with IEC 62271-1:2017;
c. the Scope has been extended to cover all indoor and outdoor installations. Consideration of switching devices having disconnecting and/or earthing switch functionalities, apart from other functions, are also covered by this document;
d. ratings have been moved from Annexes B, C and E to Clause 5; the order of the subclauses now corresponds to the order of subclauses in Clause 7;
e. new rating values for bus-transfer current and bus-transfer voltage have been assigned;
f. new class of mechanical endurance for earthing switches has been added (M1);
g. subclause Rated values of electrical endurance for earthing switches is now called Classification of earthing switches for short-circuit making capability;
h. new subclause with ratings for ice-coating has been added;
i. new subclause with classification of bus-charging switching capability has been added;
