Low-voltage switchgear and controlgear - Part 7-4: Ancillary equipment - PCB terminal blocks for copper conductors
IEC 60947-7-4:2019 is available as IEC 60947-7-4:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60947-7-4:2019 specifies requirements for PCB terminal blocks primarily intended for industrial or similar use. Mounting and fixing on the printed circuit board is made by soldering, press-in or equivalent methods to provide electrical and mechanical connection between copper conductors and the printed circuit board. This document applies to PCB terminal blocks intended to connect copper conductors, with or without special preparation, having a cross-section between 0,08 mm2 and 300 mm2 (AWG 28-600 kcmil), intended to be used in circuits of a rated voltage not exceeding 1 000 V AC up to 1 000 Hz or 1 500 V DC. This second edition cancels and replaces the first edition published in 2013. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) additional test for PCB terminal blocks with clamping units, where contact pressure is transmitted through insulating materials; b) tightening torques for screws now given in Table 4 of this document (previously given in Table 4 of IEC 60947-1:2007); tightening torques added for an additional type of screw; c) new criteria for verification of contact resistance introduced; d) clarification in the description of the temperature-rise test (current-temperature derating); corrections in the test sequence according to Figure 4.

Appareillage à basse tension - Partie 7-4: Matériels accessoires - Blocs de jonction pour cartes de circuits imprimés pour conducteurs en cuivre
IEC 60947-7-4:2019 est disponible sous forme de IEC 60947-7-4:2019 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L'IEC 60947-7-4:2018 spécifie les exigences concernant les blocs de jonction pour cartes de circuits imprimés destinés principalement à un usage industriel ou similaire. Le montage et la fixation sur la carte de circuits imprimés s'effectuent par brasage, insertion à force ou par des méthodes équivalentes afin d'assurer une connexion électrique et mécanique entre les conducteurs en cuivre et la carte de circuits imprimés. Le présent document s'applique aux blocs de jonction pour cartes de circuits imprimés destinés à connecter les conducteurs en cuivre, avec ou sans préparation spéciale, dont la section est comprise entre 0,08 mm2 et 300 mm2 (AWG 28-600 kcmil), destinés à être utilisés dans les circuits dont la tension assignée ne dépasse pas 1 000 V en courant alternatif jusqu'à 1 000 Hz ou 1 500 V en courant continu au maximum. Cette deuxième édition annule et remplace la première édition parue en 2013. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) essai complémentaire pour les blocs de jonction pour cartes de circuits imprimés à organes de serrage pour lesquels la pression de contact est transmise par des matériaux isolants; b) les couples de serrage des vis sont désormais présentés dans le Tableau 4 du présent document (ils étaient précédemment donnés dans le Tableau 4 de l'IEC 60947-1:2007); les couples de serrage sont donnés pour un type supplémentaire de vis; c) ajout de nouveaux critères pour la vérification de la résistance de contact; d) clarification de la description de l'essai d'échauffement (taux de réduction de l'intensité en fonction de la température); corrections de la séquence d'essais conformément à la Figure 4.
Nizkonapetostne stikalne in krmilne naprave - 7-4. del: Pomožna oprema - Priključni bloki na tiskanih vezjih za bakrene vodnike (IEC 60947-7-4:2019)
Ta del standarda IEC 60947-7 določa zahteve za priključne bloke na tiskanih vezjih, ki so prvotno namenjeni za industrijsko ali podobno uporabo.
Nameščanje in pritrjevanje na tiskana vezja se izvaja s spajkanjem, tiskanjem ali ekvivalentnimi metodami, da se zagotovi električni in mehanski stik med bakrenimi vodniki in tiskanim vezjem.
Ta dokument se uporablja za priključne bloke na tiskanih vezjih za povezovanje bakrenih vodnikov, s posebno pripravo ali brez nje, s prerezom med 0,08 mm2 in 300 mm2 (AWG 28–600 kcmil), namenjene za uporabo v tokokrogih, katerih nazivna napetost ne presega 1000 V izmenične napetosti s frekvenco do 1000 Hz ali 1500 V enosmerne napetosti.
OPOMBA 1: Priključni bloki z velikim prerezom so namenjeni za specifično zasnovo tiskanih vezij z visokim tokom. Vključen je razpon do 300 mm2, ki obsega katero koli posebno vrsto uporabe. Primeri tiskanih vezij z visokim tokom in priključnih blokov na tiskanih vezjih so prikazani v dodatku C.
OPOMBA 2: AWG je okrajšava za »American Wire Gage« (Gage (ZDA) = Gauge (Združeno kraljestvo)).
1 kcmil = 1000 cmil;
1 cmil = 1 krožni promil = površina kroga s premerom 1 promil;
1 mil = 1/1000 palca.
Ta dokument je mogoče uporabljati kot vodilo za posebne vrste priključnih blokov na tiskanih vezjih s komponentami, kot so odklopne enote, vgrajeni taljivi vložki varovalk in podobni, ali z drugimi dimenzijami vodnikov.
V tem dokumentu se namesto izraza »terminal« uporablja izraz »pritrdilna enota«. To se upošteva pri sklicevanju na standard IEC 60947-1.
