The breaker is designed for backplate mounting, accepts front-connect compression lugs or busbars, and occupies a 12-module 9 mm pitch width (108 mm). The grey RAL 7016 enclosure carries IP40 and IK07 ratings, so it withstands finger-probe ingress and moderate mechanical impact in an enclosed panel.
The connection pitch is 35 mm with spreaders, 27 mm without — verify busbar or lug spacing before panel layout. Neutral sits on the left. Upside and downside connections are both front-accessible, which simplifies wiring in a standard distribution board.
