The Schneider Electric A9F58363 is a 3-pole Acti9 IKQ miniature circuit breaker rated 63 A with a D tripping curve (magnetic trip threshold 10–14 × In).
The 3-pole format with toggle control and a trip indicator makes it straightforward to integrate into a panel: you see the tripped pole at a glance. Terminals accept 1–35 mm² rigid or 1–25 mm² flexible on the bottom; tighten to 3.5 N·m. IP20 rated, so it's for inside an enclosure, not washdown areas.
10,000 A Icn at 415 V AC 50/60 Hz conforming to EN 60898-1, with a service breaking capacity (Ics) of 7500 A at the same voltage.
The D curve sets the magnetic trip threshold at 10–14 times the rated current (In), so it's designed for loads with high inrush — motors, transformers, welding equipment — without nuisance tripping on startup.
