The A9S62163 is a Schneider Electric Acti9 SW single-pole switch disconnector rated 63 A at 240 V AC, with a short-circuit making capacity of 4.2 kA per IEC 60947-3. It is used for isolation and control in DIN-rail panels, with toggle actuation and tunnel terminals accepting up to 35 mm² flexible wire.
This part is marked obsolete by the manufacturer.
The AC-22A utilisation category means it is designed for switching resistive and mixed resistive-inductive loads, including moderate motor loads, at rated current. The 63 A rating at 240 V AC covers most single-phase isolation points in distribution boards. The 4.2 kA making capacity ensures it can close onto a downstream short-circuit without welding contacts, which matters for fault coordination in a panel. The 6 kV impulse withstand voltage (IEC 60947-3) confirms it handles typical surge environments in industrial and commercial installations.
Panel integration and durability
Mounts on standard DIN rail, 18 mm wide (2 x 9 mm pitches), 73 mm deep, 81 mm tall. Rated for 20,000 electrical cycles and 50,000 mechanical cycles — typical for a switch disconnector in a panel that sees daily operation. IP20 finger-safe front, pollution degree 3 (conductive pollution expected, e.g. in control cabinets near machinery). Ambient operating range -20 to 50 °C, storage -40 to 70 °C, with 95% relative humidity at 55 °C — fine for most indoor industrial environments.
