The A9KS15363BQ is a Schneider Electric Acti9 SW switch disconnector — 3 poles, rated 63 A at 415 V AC in AC-22A utilisation category, per IEC 60947-3. That AC-22A rating means it's designed for switching mixed resistive and inductive loads, including motor circuits with moderate inrush, not just pure resistive heating. It comes as a set of 4 units, each with a toggle control, tunnel terminals accepting up to 35 mm² rigid, and IP20 finger-safe enclosure for panel mounting.
Panel Integration
Each unit takes 6 x 9 mm pitches of rail width — 54 mm per pole count, so the 3-pole assembly occupies 54 mm. Tunnel terminals accept 1…35 mm² rigid or 1…25 mm² flexible, with a 9 mm strip length and 3.5 N·m tightening torque. Operating temperature range is -5…55 °C, storage -25…85 °C, with 95% humidity tolerance at 55 °C (tropicalisation class 2).
