7-4.1-1.1 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 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.
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 = 1000 cmil;
1 cmil = 1 circular mil = surface of a circle having a diameter of 1 mil
1 mil = 1/1000 inch
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 the like.
If applicable, in this standard the term “clamping unit” is used instead of “terminal”. This is taken into account in case of references to IEC 60947-1.
