(Main)Low-voltage switchgear and controlgear assemblies - Part 1: General rules (IEC 61439-1:2020)
Low-voltage switchgear and controlgear assemblies - Part 1: General rules (IEC 61439-1:2020)
This part of IEC 61439 lays down the general definitions and service conditions, construction
requirements, technical characteristics and verification requirements for low-voltage
switchgear and controlgear assemblies.
NOTE Throughout this document, the term assembly(s) (see 3.1.1) is used for a low-voltage switchgear and
controlgear assembly(s).
For the purpose of determining assembly conformity, the requirements of the relevant part of
the IEC 61439 series, Part 2 onwards, apply together with the cited requirements of this
document. For assemblies not covered by Part 3 onward, Part 2 applies.
This document applies to assemblies only when required by the relevant assembly standard
as follows:
– assemblies for which the rated voltage does not exceed 1 000 V AC or
1 500 V DC;
– assemblies designed for a nominal frequency of the incoming supply or supplies not
exceeding 1 000 Hz;
– assemblies intended for indoor and outdoor applications;
– stationary or movable assemblies with or without an enclosure;
– assemblies intended for use in connection with the generation, transmission, distribution
and conversion of electric energy, and for the control of electrical energy consuming
equipment.
This document does not apply to individual devices and self-contained components such as
motor starters, fuse switches, power electronic converter systems and equipment (PECS),
switch mode power supplies (SMPS), uninterruptable power supplies (UPS), basic drive
modules (BDM), complete drive modules (CDM), adjustable speed power drives systems
(PDS), and other electronic equipment which comply with their relevant product standards.
This document describes the integration of devices and self-contained components into an
assembly or into an empty enclosure forming an assembly.
For some applications involving, for example, explosive atmospheres, functional safety, there
can be a need to comply with the requirements of other standards or legislation in addition to
those specified in the IEC 61439 series.

Ensembles d'appareillage à basse tension - Partie 1: Règles générales (IEC 61439-1:2020)
IEC 61439-1:2020 est disponible sous forme de IEC 61439-1:2020 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.
L’IEC 61439-1:2020 formule les définitions générales et les conditions d’emploi, les exigences de construction, les caractéristiques techniques et les exigences de vérification pour les ensembles d’appareillage à basse tension. NOTE Dans le présent document, le terme ensemble(s) (voir 3.1.1) est utilisé pour désigner un ou des ensembles d’appareillage à basse tension. Dans le but de déterminer la conformité de l’ensemble, les exigences de la partie applicable de la série IEC 61439 (à partir de la Partie 2), s’appliquent, de même que les exigences citées dans le présent document. Pour les ensembles non couverts par les parties à partir de la Partie 3, la Partie 2 s’applique. Cette troisième édition annule et remplace la deuxième édition parue en 2011. Elle constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) clarification du fait que les systèmes et matériels électroniques de conversion de puissance, les alimentations à découpage, les alimentations sans interruption et les systèmes d’entraînements électriques de puissance à vitesse variable sont soumis à essai conformément à leur propre norme de produit, mais que lorsqu’ils sont incorporés dans des ensembles, l’incorporation est conforme à la série de normes IEC 61439;
b) introduction d’un courant assigné de groupe pour les circuits au sein d’un ensemble chargé et recentrage de la vérification de l’échauffement sur cette nouvelle caractéristique;
c) ajout d’exigences relatives au courant continu;
d) introduction du concept d’ensembles de classe I et de classe II en matière de protection contre les chocs électriques.
Sestavi nizkonapetostnih stikalnih in krmilnih naprav - 1. del: Splošna pravila (IEC 61439-1:2020)
Ta del standarda IEC 61439 določa splošne opredelitve in pogoje obratovanja, konstrukcijske zahteve, tehnične značilnosti ter zahteve za preverjanje na področju sestavov nizkonapetostnih stikalnih in krmilnih naprav.
OPOMBA: V tem dokumentu se izraz »sestav(-i)« (glej točko 3.1.1) uporablja za sestave nizkonapetostnih stikalnih in krmilnih naprav.
Za namene določanja skladnosti sestavov se zahteve ustreznega dela skupine standardov IEC 61439 od 2. dela naprej uporabljajo skupaj z navedenimi zahtevami tega dokumenta. Za sestave, ki niso zajeti od 3. dela naprej, se uporablja 2. del.
Ta dokument se za sestave uporablja le, kadar je to zahtevano v ustreznem standardu za sestave, kot je navedeno v nadaljevanju:
– sestavi, katerih nazivna napetost ne presega 1000 V AC ali 1500 V DC;
– sestavi, zasnovani za nazivno frekvenco vhodnega napajanja največ 1000 Hz;
– sestavi, namenjeni za notranjo in zunanjo uporabo;
– stacionarni ali premični sestavi z ohišjem ali brez njega;
– sestavi, namenjeni za uporabo na področju proizvodnje, prenosa, distribucije in pretvarjanja električne energije ter za nadzor opreme, ki uporablja električno energijo.
Ta dokument se ne uporablja za posamezne naprave in samostojne dele, kot so zaganjalniki, varovalna stikala, električni močnostni pretvorniški sistemi in oprema (PECS), stikalni napajalniki (SMPS), naprave za neprekinjeno napajanje (UPS), osnovni pogonski moduli (BDM), celoviti pogonski moduli (CDM), pogonski sistemi z nastavljivo hitrostjo (PDS) in druga elektronska oprema, ki so v skladu z njihovimi ustreznimi standardi za izdelek.
Ta dokument opisuje integracijo naprav in samostojnih delov v sestav oziroma prazen okrov, ki predstavlja sestav.
Pri nekaterih vrstah uporabe, ki vključujejo npr. eksplozivno atmosfero ali funkcijsko varnost, je poleg zahtev, določenih v skupini standardov IEC 61439, morda treba zagotoviti skladnost z zahtevami drugih standardov ali zakonodaje.
