The Schneider Electric A9S60263 is an Acti9 iSW switch disconnector rated 63 A at 415 V AC, 2 poles, for control isolation duty in panel builds. The toggle gives a clear ON/OFF indication and a contact position indicator confirms the state — useful during lockout-tagout procedures.
The 63 A rating is at 415 V AC under AC-22A utilisation category per IEC 60947-3 — that covers switching of mixed resistive and inductive loads, including moderate motor loads, but not the high inrush of heavy motors (that would be AC-23). The 6 kV impulse withstand voltage (Uimp) and 500 V insulation voltage (Ui) confirm it is suitable for isolation duty in 400 V class panels.
The 36 mm width (4 modules) fits standard distribution board cutouts.
