Based on this review, we recommend:
IEC 60947-2 specifies requirements for low-voltage circuit breakers used in industrial applications, covering devices up to 1,000 V a.c. or 1,500 V d.c.. It defines technical criteria for selectivity categories and outlines rigorous testing procedures for rated current and short-circuit capacity. For a practical, in-depth guide on the standard's application, see the BEAMA guide . IEC-60947-2-2016-AMD1-2019.pdf - iTeh Standards iec 60947-2 pdf
