EN 60947-7-2:2009

Low-voltage switchgear and controlgear - Part 7-2: Ancillary equipment - Protective conductor terminal blocks for copper conductors

IEC 60947-7-2:2009 specifies requirements for protective conductor terminal blocks with PE function up to 120 mm2 (250 kcmil) and for protective conductor terminal blocks with PEN function equal to and above 10 mm2 (AWG 8) with screw-type or screwless-type clamping units, primarily intended for industrial applications. Protective conductor terminal blocks are used to form the electrical and mechanical connection between copper conductors and the fixing support. lt is applicable to protective conductor terminal blocks for the connection of round copper conductors with or without special preparation having a cross-section between 0,2 mm2 and 120 mm2 (AWG 24 and 250 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., most commonly in conjunction with terminal blocks according to IEC 60947-7-1. This standard may be used as guide for - protective conductor terminal blocks requiring the fixing of special devices to the conductors, for example quick connect terminations or wrapped connections, etc.; - protective conductor terminal blocks providing direct contact to the conductors by means of edges or points penetrating the insulation, for example insulation displacement connections, etc. Where applicable in this standard, the term 'clamping unit' has been used instead of the term 'terminal'. This is taken into account in case of reference to IEC 60947-1. The main technical modifications of this standard since this previous publication are listed below: - requirements for tightening torques for the tests improved and referenced to Table 4 of IEC 60947-1, Annex B deleted; - the wording of the short-time withstand current test improved in 8.4.6. This publication shall be read in conjunction with IEC 60947-1:2007 and IEC 60947-7-1:2009.

Niederspannungsschaltgeräte - Teil 7-2: Hilfseinrichtungen - Schutzleiter-Reihenklemmen für Kupferleiter

Appareillage à basse tension - Partie 7-2: Matériels accessoires - Blocs de jonction de conducteur de protection pour conducteurs en cuivre

La CEI 60947-7-2:2009 spécifie les exigences pour les blocs de jonction de conducteur de protection avec la fonction PE jusqu'à 120 mm2 (250 kcmil) et pour les blocs de jonction de conducteur de protection avec la fonction PEN de section égale ou supérieure à 10 mm2 (AWG 8) avec des organes de serrage du type à vis ou du type sans vis, destinés principalement à des usages industriels. Les blocs de jonction de conducteur de protection sont utilisés afin d'assurer la connexion électrique et mécanique entre les conducteurs en cuivre et le support de fixation. Elle s'applique aux blocs de jonction de conducteur de protection pour le raccordement des conducteurs ronds en cuivre, avec ou sans préparation spéciale, de section comprise entre 0,2 mm2 et 120 mm2 (AWG 24 et 250 kcmil), prévus pour être utilisés dans des circuits de tension assignée ne dépassant pas 1 000 V à courant alternatif jusqu'à 1 000 Hz ou 1 500 V en courant continu, et très couramment avec les blocs de jonction selon la CEI 60947-7-1. La présente norme peut servir de guide pour - les blocs de jonction de conducteur de protection nécessitant la fixation de pièces spéciales sur les conducteurs, par exemple les connexions rapides ou les connexions enroulées, etc.; - les blocs de jonction de conducteur de protection assurant un contact direct avec les conducteurs au moyen de lames ou de pointes pénétrant à travers l'enveloppe isolante, par exemple les connexions par déplacement d'isolant, etc. Dans la présente norme, le terme 'organe de serrage' a été utilisé, s'il y a lieu, à la place du terme 'borne'. Cela est pris en compte en cas de référence à la CEI 60947-1. Les modifications techniques majeures de la présente norme depuis la précédente publication sont listées ci-dessous: - les exigences concernant les couples de serrage pour les essais ont été améliorées et référencées au Tableau 4 de la CEI 60947-1 et l'Annexe B a été supprimée; - en 8.4.6 la rédaction de l'essai du courant assigné de courte durée admissible a été amélioré. Cette publication doit être lue conjointement avec la CEI 60947-1:2007 et la CEI 60947-7-1:2009.
