The Schneider Electric ENW24191 is a 4-pole fixed-mount switch disconnector from the EasyPact NW range, rated 1250 A in AC-23A duty at 690 V AC. It's also marked suitable for isolation per IEC 60947-3, so you can use it as a visible-break disconnecting means for a panel or machine.
Ratings that matter for the panel
The 1250 A rating at 690 V AC is the headline number, but the short-time withstand (Icw) tells you how it handles a fault before the upstream breaker clears: 50 kA for 1 second, or 25 kA for 3 seconds, per IEC 60947-3. That's the figure your coordination study uses. The making capacity (Icm) is 105 kA peak — meaning it can close onto a bolted fault without welding its contacts. Impulse withstand (Uimp) is 12 kV, which covers most 690 V industrial installations. Pollution degree 4 per IEC 60664-1 means it's rated for harsh environments with conductive dust or condensation — not just a clean control room.
Physical fit and mounting
Fixed-mount on a base plate, rear-connected. The footprint is 537 mm wide by 352 mm tall by 297 mm deep — that depth matters if you're shoehorning it into an existing enclosure with limited clearance behind the door. Connection pitch is 115 mm without a spreader. Neutral position is left.
