The Schneider Electric A9S68492 is a 4-pole switch disconnector from the Acti9 iINT range, rated for 125 A at 400 V AC in AC-22A utilisation category. That AC-22A rating means it's designed for switching mixed resistive and inductive loads, including motor loads at moderate switching frequencies — the standard duty for control isolation in distribution panels.
Mounts fixed on DIN rail, occupying 72 mm width and 85 mm height with a 73 mm depth — a standard 4-module footprint that fits alongside MCBs and RCDs in a distribution board. The tunnel-type terminals accept 6…50 mm² rigid or 6…35 mm² flexible cable, which is generous for the 125 A rating and allows paralleling of supply conductors if needed.
Electrical ratings and isolation suitability
The switch is explicitly suitable for isolation with a visible contact position indicator and ON/OFF local signalling. Short-time withstand current [Icw] is 1500 A, and the short-circuit making capacity [Icm] is 5 kA for the switch-disconnector alone — adequate for most sub-distribution applications where upstream protection is a suitably rated MCCB or fuse.
