The Schneider Electric A9S60463 is an Acti9 iSW switch disconnector with 4 poles, rated 63 A at 415 V AC (IEC 60947-3). It's designed for isolation and control in DIN-rail panels, with a toggle mechanism and ON/OFF indication. The AC-22A utilisation category means it's suited for switching mixed resistive and inductive loads, including motor circuits with moderate starting currents, up to the 63 A mark.
The 6 kV impulse withstand voltage (Uimp) and pollution degree 3 rating confirm it holds up in industrial environments with moderate conductive contamination. The 500 V insulation voltage (Ui) gives headroom for 400 V class systems. Mechanical durability of 50,000 cycles and electrical durability of 20,000 cycles set the expected service life under rated switching.
The 4-pole footprint takes 72 mm width on the rail — 8 modules of 9 mm pitch. IP4 protection means it's splash-resistant but not washdown-rated — keep it inside the enclosure.
