IEC 62271-105:2012 applies to three-pole units for public and industrial distribution systems which are functional assemblies of switches including switch-disconnectors and current-limiting fuses designed so as to be capable of
\n– breaking, at the rated recovery voltage, any current up to and including the rated short-circuit breaking current;
\n– making, at the rated voltage, circuits to which the rated short-circuit breaking current applies.
\nIt does not apply to fuse-circuit-breakers, fuse-contactors, combinations for motor-circuits or to combinations incorporating single capacitor bank switches. This second edition cancels and replaces the first edition of IEC 62271-105, published in 2002, and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
\n– implementation of figures at the place where they are cited first;
\n– renumbering of tables;
\n– addition of some of the proposals from IEC paper 17A\/852\/INF;
\n– addition of missing subclauses of IEC 62271-1;
\n– implementation of 6.105 "Extension of validity of type tests" and consequently removing of the relevant parts in the different existing clauses;
\n– change of 7th paragraph of 6.101.4 as there is now a definition of NSDD given in 3.7.4 of IEC 62271-1:2007. Harmonization with IEC 62271-107;
\n– some referenced clauses in other standards like IEC 60282-1 were changed and therefore changed the editions under 1.2 to the ones referred to;
\n– addition of a new Annex C defining tolerances.<\/p>\n

This publication is to be read in conjunction with IEC 62271-1:2007.<\/p>\n","protected":false},"excerpt":{"rendered":"
