Low-voltage switchgear and controlgear assemblies - Part 1: General rules
IEC 61439-1:2009 lays down the definitions and states the service conditions, construction requirements, technical characteristics and verification requirements for low-voltage switchgear and controlgear assemblies. This standard applies to low-voltage switchgear and controlgear assemblies (ASSEMBLIES) only when required by the relevant ASSEMBLY standard. This first edition of IEC 61439-1 standard cancels and replaces the fourth edition of IEC 60439-1:1999. Significant technical changes with respect to the last edition of IEC 60439-1. IEC 61439-1 is a pure 'general rules' standard to be referred to by subsidiary product parts of the IEC 61439 series; the product standard replacing IEC 60439-1 is IEC 61439-2; the discrimination between type-tested assemblies (TTA) and partially type-tested assemblies (PTTA) is eliminated by the verification approach; three different but equivalent types of verification of requirements are introduced: verification by testing, verification by calculation/measurement, or verification by satisfying design rules; the requirements regarding temperature rise have been clarified; the rated diversity factor (RDF) is covered in more detail; requirements from the standard for empty enclosures for assemblies (IEC 62208) have been incorporated; the whole structure of the standard is aligned with its new function as 'general rules' standard. However, when a dated reference to IEC 60439-1 is made in another Part of the IEC 60439 series of assembly standards not yet transferred into the new IEC 61439 series, the superseded IEC 60439-1 still applies.
Niederspannungs-Schaltgerätekombinationen - Teil 1: Allgemeine Festlegungen
Ensembles d'appareillage à basse tension - Partie 1: Règles générales
La CEI 61439-1:2009 formule les définitions et indique les conditions d'emploi, les exigences de construction, les caractéristiques techniques et les exigences de vérification pour les ensembles d'appareillage à basse tension. La présente norme s'applique, uniquement lorsque la norme d'ENSEMBLES applicable l'exige, aux ensembles d'appareillage à basse tension (ensembles). Cette première édition de la CEI 61439-1 annule et remplace la quatrième édition de la CEI 60439-1 :1999. Les modifications techniques sont les suivantes par rapport à la dernière édition de la CEI 60439-1. La CEI 61439-1 est une norme purement de 'règles générales' devant être appelée par les parties de produit subsidiaires de la série CEI 61439; la norme de produit remplaçant la CEI 60439-1 est la CEI 61439-2; la distinction entre les ensembles de série (ES) et les ensembles dérivés de série (EDS) est éliminée par l'approche de vérification; trois types différents mais équivalents de vérification des exigences sont introduits: la vérification par essai, la vérification par calcul/mesure, ou la vérification par la satisfaction de règles de conception; les exigences concernant les échauffements ont été clarifiées; le facteur de diversité assigné (RDF) est traité avec de plus amples détails; les exigences des enveloppes vides destinées aux ensembles (CEI 62208) ont été incorporées; la totalité de la structure de la norme est alignée avec sa nouvelle fonction comme norme de 'règles générales'. Toutefois, lorsqu'une référence datée à la CEI 60439-1 apparaît dans une autre partie de la série CEI 60439 applicable aux ensembles qui n'a pas encore été transposée dans la nouvelle série CEI 61439, c'est la norme annulée CEI 60439-1 qui continue de s'appliquer.
Sklopi nizkonapetostnih stikalnih in krmilnih naprav - 1. del: Splošna pravila
IEC 61439-1:2009 določa opredelitve in navaja servisne pogoje, konstrukcijske zahteve, tehnične karakteristike in verifikacijske zahteve za sklope nizkonapetostnih stikalnih in krmilnih naprav. Ta standard velja za sklope nizkonapetostnih stikalnih in krmilnih naprav (SKLOPE) le, kadar tako zahteva ustrezni standard za SKLOPE. Ta prva izdaja IEC 61439-1 razveljavlja in nadomešča četrto izdaja IEC 60439-1:1999. Bistvene tehnične spremembe glede na zadnjo izdajo IEC 60439-1. IEC 61439-1 je standard s popolnoma 'splošnimi pravili', na katerega se sklicujejo deli serije IEC 61439 za pomožne proizvode; standard za proizvode, ki nadomešča IEC 60439-1, je IEC 61439-2; razlikovanje med tipsko preskušenimi (TTA) in delno tipsko preskušenimi sklopi (PTTA) se odpravi z verifikacijskim pristopom; uvedene so tri različne, a enakovredne vrste zahteva za verifikacijo: verifikacija s preskušanjem, verifikacija z izračunom/merjenjem ali verifikacija z izpolnjevanjem pravil za načrtovanje; pojasnjene so zahteve za naraščanje temperature; podrobneje je opisan faktor nazivne neenakosti (RDF); vključene so zahteve standarda za prazne ograjene prostore za sklope (IEC 62208); celotna struktura standarda je usklajena z novo funkcijo standarda 'splošnih pravil'. Ob sklicevanju na IEC 60439-1 v drugem delu serije IEC 60439 za standarde sklopov, ki še ni prenesen v novo serijo 61439, še vedno velja nadrejeni IEC 60439-1.

SIST EN 61439-1:2010
EN 61439-1:2009 – 2 – Foreword The text of the International Standard IEC 61439-1:2009, prepared by SC 17D, Low-voltage switchgear and controlgear assemblies, of IEC TC 17, Switchgear and controlgear, together with the common modifications prepared by the Technical Committee CENELEC TC 17D, Low-voltage switchgear and controlgear assemblies, was submitted to the formal vote and was approved by CENELEC as EN 61439-1 on 2009-11-01. This European Standard supersedes EN 60439-1:1999 + A1:2004. This European Standard includes the following significant technical changes with respect to EN 60439-1:1999: – the dual role of EN 60439-1 as a product standard in its own right, as well as a general rules standard for assemblies covered by a subsidiary product part of the EN 60439 series, has been abandoned; – consequently, EN 61439-1 is a pure “general rules” standard to be referred to by subsidiary product parts of the EN 61439 series; – the product standard replacing EN 60439-1 is EN 61439-2; – the discrimination between type-tested assemblies (TTA) and partially type-tested assemblies (PTTA) is eliminated by the verification approach; – three different but equivalent types of verification of requirements are introduced:
≤ verification by testing,
≤ verification by calculation/measurement, or
≤ verification by satisfying design rules; – the requirements regarding temperature rise have been clarified; – the rated diversity factor (RDF) is covered in more detail; – requirements from the standard for empty enclosures for assemblies (EN 62208) have been incorporated; – the whole structure of the standard is aligned with its new function as “general rules” standard. 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)
2010-11-01 – latest date by which the national standards conflicting with the EN have to be withdrawn
(dow)
2014-11-01 However, when a dated reference to EN 60439-1 is made in another part of the EN 60439 series of assembly standards not yet transferred into the new EN 61439 series, the superseded EN 60439-1 still applies (see also the Introduction). This European Standard has been prepared under a mandate given to CENELEC by the European Commission and the European Free Trade Association and covers essential requirements of EC Directive EMC (2004/108/EC). See Annex ZZ. Annexes ZA and ZZ have been added by CENELEC. ___________ SIST EN 61439-1:2010
