EN 60947-7-4:2013

Low-voltage switchgear and controlgear - Part 7-4: Ancillary equipment - PCB terminal blocks for copper conductors

IEC 60947-7-4:2013 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 standard applies to PCB terminal blocks intended to connect copper conductors, with or without special preparation, having a cross-section between 0,05 mm2 and 300 mm2 (AWG 30/600 kcmil), intended to be used in circuits of a rated voltage not exceeding 1 000 V a.c. up to 1 000 Hz or 1 500 V d.c.

Appareillage à basse tension - Partie 7-4: Matériels accessoires - Blocs de jonction pour cartes de circuits imprimés pour conducteurs en cuivre

La CEI 60947-7-4:2013 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. La présente norme 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 0,05 mm2 et 300 mm2 (AWG 30/600 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.

Nizkonapetostne stikalne in krmilne naprave - 7-4. del: Pomožna oprema - Priključni bloki na tiskanih vezjih za bakrene vodnike (IEC 60947-7-4:2013)

Ta del standarda IEC 60947 navaja 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 standard velja za priključne bloke na tiskanih vezjih za povezovanje bakrenih vodnikov, s posebno pripravo ali brez nje, s prerezom med 0,05 mm2 in 300 mm2 (AWG 30/600 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.
