Scope
This document specifies the requirements for PCB terminal blocks intended primarily for industrial or similar purposes. Copper conductors are mounted or fixed on a printed circuit board by soldering, pressing or equivalent means so that an electrical or mechanical connection is made between the two. This document is applicable to circuits with rated voltage AC not exceeding 1000V, frequency up to 1000 Hz or DC not exceeding 1500V, used to connect treated or untreated copper conductors with a cross-sectional area of 0.08mm2 ~ 300mm2 (AWG28/600kcmil) PCB terminal blocks. Note 1: Large cross-section terminal blocks are specially designed for high-current PCBs. Keep the cross-sectional area to a maximum of 300 mm2 to cover all possible uses. See Appendix C for examples of high current PCBs and PCB terminal blocks. Note 2: AWG is the abbreviation of "American Wire Gauge"; 1kcmi l=1000cmi l=0.507 mm2; 1cmi l=1 circular mil=circular area with a diameter of 1 mil; 1 mi l=1/1000 inch=0.0254 mm. This document serves as a guide for special types of PCB terminal blocks with components (isolators, integral tubular fuse-links and similar components or wires with other sizes, etc.). Where applicable, when referring to IEC 60947 1:2020, the term "clamping member" is used in this document instead of "terminal".
