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

EN IEC 60947-7-4-2019 发布历史

This part of IEC 60947-7 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. NOTE 1 Large-cross-section terminal blocks are dedicated to the 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. NOTE 2 AWG is the abbreviation of ??American Wire Gage?? (Gage (US) = Gauge (UK)). 1 kcmil = 1 000 cmil; 1 cmil = 1 circular mil = surface of a circle having a diameter of 1 mil; 1 mil = 1/1 000 inch. This document can be used as a guide for special types of PCB terminal blocks with components@ such as disconnect units@ integrated cartridge fuse-links and the like or with other dimensions of conductors. If applicable@ in this document the term ??clamping unit?? is used instead of ??terminal??. This is taken into account in the case of references to IEC 60947-1.
