Switch disconnector for control circuits — 40 A at 415 V, AC-22A
The Schneider Electric A9KS15240BQ is an Acti9 SW switch disconnector rated 40 A at 415 V AC in AC-22A utilisation category, meaning it handles mixed resistive and inductive loads typical of control circuits — motor starters, contactor coils, and distribution subfeeds — but is not rated for motor switching under full load (that would be AC-23A or AC-3). Two-pole isolation, 36 mm wide per DIN-rail mounting, set of six units per order code.
Fixed DIN-rail mount, 4 module pitches at 9 mm each. Strip 9 mm, torque to 3.5 N·m. IP20 finger-safe front, IP40 inside the enclosure — no washdown rating, keep it in a cabinet.
