scope:

This part of IEC 60947 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 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)); 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 may 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 case of references to IEC 60947-1.
