Niederspannungsschaltgeräte - Teil 7-4: Hilfseinrichtungen - Leiterplatten-Anschlussklemmen für Kupferleiter (IEC 60947-7-4:2013); Deutsche Fassung EN 60947-7-4:2013
Overview
This standard is a new part of the series IEC 60947-7. It 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. Large cross section terminal blocks are dedicated to specific design of high current PCBs. The range up to 300 mm2 is kept to cover any possible application. Examples of high current PCBs and PCB terminal blocks are shown in Annex C of the draft. This standard may be used as a guide for special types of PCB terminal blocks with components, such as disconnect units, integrated cartridge fuse-links and components. The responsible committee is DKE/K 431 "Niederspannungsschaltgeräte und -kombinationen" ("Low-voltage switchgear and controlgear assemblies") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
