The 4P (4-pole) switching with neutral left matches standard 3-phase + N busbar layouts. The breaker is category A (no intentional short-time delay), so it's for instantaneous trip coordination, not selective with downstream breakers.
This breaker is designed for distribution in commercial and industrial panels — backplate-mounted, front-connected, with compression lug or busbar terminals. The IP40 front face and IK07 impact rating suit indoor switchgear where occasional tool contact is possible. Pollution degree 3 (IEC 60664-1) means it handles conductive pollution typical in industrial environments. The 12-module 9 mm pitch (108 mm wide) fits standard DIN-rail enclosures.
