Low-voltage switchgear and controlgear - Part 2: Circuit-breakers

IEC 60947-2:2016 is available as IEC 60947-2:2016 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 60947-2:2016 applies to circuit-breakers, the main contacts of which are intended to be connected to circuits, the rated voltage of which does not exceed 1 000 V a.c. or 1 500 V d.c.; it also contains additional requirements for integrally fused circuit-breakers. This fifth edition cancels and replaces the fourth edition published in 2006, Amendment 1:2009 and Amendment 2:2013. This edition constitutes a technical revision. This edition includes the following significant additions with respect to the previous edition: - tests for verification of selectivity in Annex A (see A.5.3); - critical load current tests for d.c. circuit-breakers (see 8.3.9); - new Annex P for circuit-breakers for use in photovoltaic applications; - new Annex R for residual-current circuit-breakers with automatic reclosing functions.

Niederspannungsschaltgeräte - Teil 2: Leistungsschalter

Appareillage à basse tension - Partie 2: Disjoncteurs

L'IEC 60947-2:2016 est applicable aux disjoncteurs dont les contacts principaux sont destinés à être reliés à des circuits dont la tension assignée ne dépasse pas 1 000 V en courant alternatif ou 1 500 V en courant continu; elle contient aussi des exigences supplémentaires pour les disjoncteurs à fusibles incorporés. Cette cinquième édition annule et remplace la quatrième édition parue en 2006, l'Amendement 1:2009 et l'Amendement 2:2013. Cette édition constitue une révision technique. Cette édition inclut les additions techniques majeures suivantes par rapport à l'édition précédente: - essais pour la vérification de la sélectivité dans l'Annexe A (voir A.5.3), - essais de courants de charge critiques pour disjoncteurs à courant continu (voir 8.3.9), - nouvelle Annexe P relative aux disjoncteurs pour utilisation dans des applications photovoltaïques, - nouvelle Annexe R relative aux disjoncteurs de courant différentiel résiduel avec fonctions de refermeture automatique.

Nizkonapetostne stikalne naprave - 2. del: Odklopniki (IEC 60947-2:2016)

Zahteve in preskusne metode za odklopnike, ki vključujejo zaščito pred preostalim tokom z avtomatskim ponovnim vklopom, so v dodatku R.
Dodatne zahteve za odklopnike, ki se uporabljajo kot neposredni zaganjalniki, so podane v standardu IEC 60947-4-1, ki se uporablja za nizkonapetostne kontaktorje in zaganjalnike.
Zahteve za odklopnike za zaščito žičnih inštalacij v stavbah ter podobni načini uporabe in odklopnike, ki jih bodo uporabljale nepoučene osebe, so zajete v standardu IEC 60898.
Zahteve za odklopnike za opremo (npr. za električne aparate) so zajete v standardu IEC 60934.
Za določene uporabe (npr. vleka, valjarne, storitve v marinah) lahko veljajo posebne ali dodatne zahteve.
OPOMBA: Odklopniki, ki so obravnavani v tem standardu, imajo lahko naprave za avtomatsko odpiranje v vnaprej določenih pogojih, ki so drugačni od tistih za prenapetost in podnapetost, kot je sprememba moči ali toka. Ta standard ne obravnava preverjanja delovanja v takih vnaprej določenih pogojih.
Namen tega standarda je navesti:
a) značilnosti odklopnikov;
b) pogoje, s katerimi morajo odklopniki izpolnjevati zahteve glede na:
1) delovanje in obnašanje v običajnih pogojih;
2) delovanje in obnašanje pri preobremenitvi ter delovanje in obnašanje v primeru kratkega stika, vključno s koordinacijo delovanja (selektivnost in varnostna zaščita);
3) dielektrične lastnosti;
c) preskuse, katerih namen je potrditi, da so bili ti pogoji in metode izvajanja teh preskusov izpolnjeni;
d) podatke, ki jih je treba označiti na napravi ali jih priložiti napravi.
