Switch disconnector for distribution, 1600 A, AC-23A
The Schneider Electric ENW24176 is a fixed-mount switch disconnector from the EasyPact NW range, rated 1600 A in AC-23A duty at 690 V AC. That AC-23A utilisation category means it handles switching of motors and other highly inductive loads — not just resistive break — so it's suited for distribution panels feeding motor control centres or large transformer loads.
Withstand and making capacity
Rated short-time withstand current (Icw) is 50 kA for 1 s or 25 kA for 3 s at the full operating temperature range (-5 to 70 °C). That gives protection coordination engineers a solid window for upstream breaker clearing times. The rated short-circuit making capacity (Icm) is 105 kA at 50/60 Hz — meaning it can close onto a fault without welding contacts, which matters when you're restoring power after a trip.
Physical integration and environment
Footprint is 422 mm wide by 352 mm high by 297 mm deep — a substantial unit that bolts to a base plate (fixed mounting, not DIN rail). Connection is rear-entry, horizontal or vertical orientation, with a 115 mm pitch without spreader.
