The ENW24190 is a Schneider Electric EasyPact NW switch disconnector rated for 1000 A in AC-23A duty at 690 V AC. The 4-pole (4P) configuration with neutral on the left makes it a straight fit for three-phase-plus-neutral distribution panels.
The headline 1000 A AC-23A at 690 V is the operational current under the heaviest switching duty — motor starting, frequent on-load making and breaking. For isolation duty (which this device is certified for per IEC 60947-3), the continuous current rating applies across the full 1000 V insulation voltage (Ui). The short-time withstand (Icw) of 50 kA for 1 s or 25 kA for 3 s tells you the bus can ride through a fault without welding contacts — critical for selective coordination in a distribution board. The making capacity (Icm) of 105 kA peak confirms it can close onto a bolted fault without damage. Pollution degree 4 per IEC 60664-1 means this switch is rated for harsh environments — conductive dust or condensation — so it suits unheated electrical rooms or outdoor enclosures. The IP40 enclosure protection keeps tools and fingers out but is not washdown-rated; mount it in a cabinet if the environment is wet.
Fixed mounting on a base plate, rear connection terminals with a 115 mm pitch without spreader. The 537 mm width and 352 mm height mean it fills a standard cubicle section — plan for a 600 mm wide panel bay. Horizontal or vertical connection orientation is acceptable; the rear-entry layout keeps cables out of the front access zone.
