It switches supply sources in AC panels — think generator-to-mains or utility-to-backup transfer in a DIN-rail enclosure. The utilisation categories AC-22A (resistive/mixed loads) and AC-23A (motor loads with occasional overloads) tell you it handles both lighting and small motor circuits, but the 63 A rating and 7.8 kW at 240 V (AC-23A) give the real bound: it's sized for a sub-feed or a machine isolator, not a main breaker. The 63 A rated operational current (Ie) is the continuous current the switch can carry in normal service — not a making-capacity figure. The short-time withstand current (Icw) of 1.26 kA for 1 s means the switch can survive a downstream fault until the upstream protection clears, but it's not a short-circuit breaking device — you need a separate MCB or fuse ahead of it. The 6 kV rated impulse withstand voltage (Uimp) confirms it's suitable for standard 400/480 V distribution panels even though the operational voltage is 230/240 V. Snaps onto 35 mm DIN rail, occupies 3 x 9 mm pitches (26.25 mm wide). The toggle is a 3-position white control (I-O-II), and a padlock can lock it in the ON position. Screw terminals accept 1...25 mm² rigid or 1...16 mm² flexible (with or without ferrule); tighten to 4 N·m. Strip length 12 mm. IP20 body, IP40 inside an enclosure — so it needs a panel or cabinet for washdown areas. Mount vertically or in any position, but vertical is standard for thermal performance.","metaTitle":"Schneider Electric A9SCO163 Acti9 iSSW Changeover Switch, 1P","metaDescription":"Schneider Electric A9SCO163 Acti9 iSSW changeover switch, 1P, 63 A, 230/240 VAC.
