The Schneider Electric ENW24185 is a 4-pole switch disconnector from the EasyPact NW family, rated for 2000 A continuous duty in AC-23A utilisation at 690 V AC. It's a drawout unit — mounts on a rail, rear-connected, with the neutral on the left. That AC-23A rating means it's built to handle motor loads and other high-inrush switching, not just resistive circuits. The 50 kA short-time withstand for 1 second (105 kA making capacity) tells you it can ride through a fault without welding contacts, which is the kind of margin a distribution panel needs when the upstream breaker isn't sized tight.
The 1000 V rated insulation voltage (Ui) and 12 kV impulse withstand (Uimp) confirm this switch is suitable for isolation per IEC 60947-3 — you can lock it out and work downstream with confidence. The IP40 enclosure keeps fingers and tools out but isn't sealed against water, so it belongs inside a cabinet, not out on the floor.
