Changeover switch, 63 A, 400/415 VAC — Acti9 iSSW
The Schneider Electric A9SCO263 is an Acti9 iSSW changeover switch, 2-pole, rated 63 A at 400/415 VAC. It switches between two supply sources — mains and generator, or two utility feeds — in a panel where isolation and load-break are required. The AC-23A utilisation category (7.8 kW at 240 V, 7.5 kW at 230 V) covers motor loads with occasional switching; AC-22A (12 kW at 240 V, 11.6 kW at 230 V) covers mixed resistive and inductive loads. It is suitable for isolation and carries a padlockable ON position.
