This is the figure that governs coordination with upstream switchgear; a standard 25 kA MCCB would cascade failure here. The 4-pole (4P) configuration with neutral on the left and front-connect terminals (compression lug or busbar) suits it for three-phase plus neutral panels where all poles are switched and protected. IP40 front face and IK07 impact rating mean it's safe in a locked enclosure but not washdown — keep it dry.
Mounts on a backplate (not DIN rail) — 12 module pitches at 9 mm each, so it occupies 108 mm of panel width. Height is 137 mm, depth 80 mm. Connection pitch is 35 mm with spreaders, 27 mm without. Can be mounted horizontally or vertically flat on the backplate. Pollution degree 3 (IEC 60664-1) means it's rated for conductive dust environments typical in industrial panels.
