Control isolation switch disconnector, 1P, 100 A, AC-22A
The Schneider Electric A9S68191 is a 1-pole Acti9 iINT switch disconnector rated 100 A at 230 V AC and 240 V operational voltage, in utilisation category AC-22A for switching resistive and mixed resistive-inductive loads including moderate motor loads. It is designed for control isolation duty and certified for isolation per GB 14048.3, with a visible contact gap and ON/OFF indication confirming the disconnected state.
The AC-22A utilisation category (100 A at 230 V) covers on/off switching of resistive and mixed loads including small motors, heaters, and lighting banks — the most common duty for a panel isolation switch. Rated insulation voltage is 250 V AC with a 6 kV impulse withstand, so it is sized for 240 V line-to-neutral circuits in pollution degree 3 environments (industrial panels with conductive contamination).
Tunnel-type terminals accept 6 to 50 mm² rigid or 6 to 35 mm² flexible conductors (with or without ferrule), with a 14 mm strip length and 3.5 N.m tightening torque. The 18 mm width on DIN rail leaves room for adjacent devices in a crowded enclosure. Top or bottom busbar and distribution-block compatibility is confirmed, so common power distribution schemes work without extra adapters.
