High-voltage switchgear and controlgear - Part 105: Alternating current switch-fuse combinations

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 - breaking, at the rated recovery voltage, any current up to and including the rated short-circuit breaking current, - making, at the rated voltage, circuits to which the rated short-circuit breaking current applies. It does not apply to fuse-circuit-breakers, fuse-contactors, combinations for motor-circuits or to combinations incorporatingsingle capacitor bank switches.

Appareillage à haute tension - Partie 105: Combinés interrupteurs-fusibles pour courant alternatif

Est applicable aux appareils tripolaires utilisés dans les réseaux de distribution publics ou les installations industrielles, appareils formant des ensembles fonctionnels composés d'interrupteurs ou d'interrupteurs-sectionneurs et de fusibles limiteurs de courant conçus pour être capable de - couper, à la tension de rétablissement assignée, tous les courants jusques et y compris le pouvoir de coupure assigné, - établir, à la tension assignée, des circuits pour lesquels le pouvoir de coupure assigné s'applique. Elle ne s'applique ni aux combinés disjoncteurs-fusibles, ni aux contacteurs-fusibles, ni aux combinés destinés à la manoeuvre et à la protection des moteurs ou des batteries de condensateurs.

This European Standard was approved by CENELEC on 2002-10-01. CENELEC members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.
Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the Central Secretariat or to any CENELEC member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CENELEC member into its own language and notified to the Central Secretariat has the same status as the official versions.
CENELEC members are the national electrotechnical committees of Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and United Kingdom.

This European Standard supersedes EN 60420:1993.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement
(dop) 2003-12-01
– latest date by which the national standards conflicting with the EN have to be withdrawn

2005-10-01
This European Standard is to be used in conjunction with EN 60694:1996 to which it refers and which is applicable, unless otherwise specified. In order to simplify the indication of corresponding requirements, the same numbering of clauses and subclauses is used as in EN 60694. Additional subclauses are numbered from 101.
Annexes designated "normative" are part of the body of the standard.
Annexes designated "informative" are given for information only.
In this standard, annexes
B and ZA are normative and annex A is informative. Annex ZA has been added by CENELEC.
The numbering of the standards falling under the responsibility of IEC/SC 17A and IEC/SC 17C will apply the following principle:
a) Common standards prepared by SC 17A and SC 17C will start with IEC 62271-001; b) Standards of SC 17A will start with IEC 62271-100; c) Standards of SC 17C will start with IEC 62271-200; d) Guides prepared by SC 17A and SC 17C will start with IEC 62271-300.
