Switch disconnector for isolation and control
The Schneider Electric A9S68192 is a single-pole switch disconnector from the Acti9 iINT series, rated for 125 A at 230 V AC and 240 V AC operational voltage. It is designed for isolation and control duties, with a utilisation category of AC-22A — meaning it is suited for switching resistive and mixed loads, including moderate motor loads, up to its rated current. The part carries a suitability-for-isolation marking and a visible contact position indicator, per the datasheet.
DIN rail integration and panel fit
The 18 mm width (1 module pitch) and 85 mm height fit a compact panel layout; depth is 73 mm, which must be accounted for when sizing the enclosure depth against the gland plate or back panel. The tunnel-type terminals accept 6–50 mm² rigid or 6–35 mm² flexible conductors, with a stripping length of 14 mm and tightening torque of 3.5 N·m.
Rated insulation voltage (Ui) is 250 V AC; impulse withstand voltage (Uimp) is 6 kV. Short-time withstand current (Icw) is 1500 A, and short-circuit making capacity (Icm) is 5 kA for the switch-disconnector alone — this defines the fault-clearing capability when used without an upstream fuse or breaker. The part is rated for pollution degree 3 (industrial environment) and operates between -25 °C and 60 °C ambient, with storage from -40 °C to 85 °C.
