Rated for isolation per IEC 60947-2, so it doubles as a visible-break disconnect when the toggle is off — no separate switch needed upstream for routine isolation.
The 160 A frame (NSXm 160E) is the smallest in the ComPacT NSXm range, sized for 12 module pitches at 9 mm each (108 mm wide) — it fits standard backplate mounting in enclosures where panel width is tight. The TM-D trip unit is thermal-magnetic, category A (no intentional short-time delay), so it coordinates downstream with standard MCBs but not with time-delayed breakers upstream. Front connection terminals accept compression lugs or busbars; the neutral is fixed on the left, and the breaker mounts horizontally or vertically flat on the backplate. IP40 front face and IK07 impact resistance handle accidental tool contact in a closed panel — not rated for washdown, but fine for indoor switchgear.
