Above that, derate per the thermal curve in the datasheet. The 3-pole configuration (3P) covers three-phase loads. The TM-D trip unit is fixed, non-interchangeable, so what you order is what you get — no field-swap of trip curves.
Mounts on a backplate (not DIN rail) — the 9-module pitch at 81 mm width and 137 mm height fits standard distribution board cutouts. Connection is front-face on both line and load sides, using compression lugs or busbars. The 35 mm connection pitch with spreaders (27 mm without) matches common busbar systems. IP40 front-of-panel protection means it is splash-resistant from the front but not sealed — keep it inside the enclosure, not in a washdown zone. The grey RAL 7016 colour is the standard Schneider panel aesthetic. The flag indicator (green) shows auxiliary contact status at a glance.
