Deployed at the main distribution level for high-current applications up to 6,300 A.

IEC 60947-2 is a specific part of the broader IEC 60947 series, which covers low-voltage switchgear and controlgear. While other parts of the series handle switches, disconnectors, and motor starters, Part 2 focuses exclusively on whose main contacts are intended to be connected to circuits with rated voltages up to 1,000 V AC or 1,500 V DC. iec 60947-2 pdf
