The Schneider Electric A9S70690 is an Acti9 iSW-NA switch disconnector rated for 100 A at 230/240 V AC 50/60 Hz, in a 1P+N pole configuration. It is designed for isolation and control duties, certified to EN/IEC 60947-3, and carries an AC-22A utilisation category — meaning it is suited for switching mixed resistive and inductive loads, including motor circuits within its rating, with a making and breaking capacity that covers normal service conditions. The 100 A rating at 230/240 V AC is the headline figure for BOM fit; verify your load type against the AC-22A curve.
For motor loads, the AC-22A category covers switching of mixed loads including motors up to the rated current — but if your application requires frequent motor starting under full load, check the AC-23 category rating (not listed here) for a higher making capacity. The short-time withstand current (Icw) of 1.5 kA for 1 second and short-circuit making capacity (Icm) of 5 kA (switch-disconnector alone) define its fault-handling capability: it can close onto a fault up to 5 kA and withstand 1.5 kA for 1 second without damage, which is typical for a panelboard feeder switch. The neutral position is left, and the device provides local ON/OFF indication and a contact position indicator — so an operator can visually confirm the state without relying on a panel lamp.
Tunnel-type terminals accept cables up to 35 mm² rigid or 25 mm² flexible (with or without ferrule), with a tightening torque of 3.5 N·m and a wire stripping length of 14 mm. The terminals are accessible from top or bottom, and the switch is compatible with comb busbars on either side — so it can be fed from a busbar system or individually wired.
