Scope

This document specifies the requirements for PCB wiring terminal blocks primarily used in industrial or similar applications. Copper conductors are installed or fixed on printed circuit boards by brazing, insertion, or equivalent methods, thereby establishing an electrical or mechanical connection between the two. This document applies to circuits with a rated voltage of AC not exceeding 1,000 V and a frequency up to 1,000 Hz, or DC not exceeding 1,500 V, for connecting processed or unprocessed copper conductors with a cross-sectional area of 0.08 mm2 to 300 mm2 (AWG 28/600 kcmil) on PCB wiring terminal blocks.
