The ENW24203 is a 3-pole switch disconnector from the Schneider Electric EasyPact NW range, rated 3200 A in AC-23A duty at 690 V AC. That AC-23A utilisation category means it handles switching of motor loads and other highly inductive circuits — not just resistive break — so it's specified for distribution panels where the load side includes motors, transformers, or capacitor banks. The drawout mounting lets you rack the unit out for maintenance without disturbing the bus connections, which is standard for high-current switchgear where downtime for isolation needs to be measured in minutes, not hours. Rated short-time withstand current (Icw) is 66 kA for 1 second, or 36 kA for 3 seconds — this tells you the disconnector can survive a fault current long enough for an upstream breaker to clear it, which is the selectivity requirement for a distribution feeder. The making capacity (Icm) is 143 kA peak, so it can close onto a fault without welding contacts. That combination of ratings puts this squarely in heavy industrial switchgear, not light commercial.
Drawout mounting on a rail with rear connection. The connection pitch is 115 mm without a spreader, which is the centre-to-centre spacing for the rear bus stabs — verify your panel busbar centres match before specifying. Dimensions: 441 mm wide, 439 mm high, 395 mm deep. The depth is the projection behind the panel face for the drawout cradle. Electrical durability at 440 V AC-23A is 5,000 cycles without maintenance; at 690 V it drops to 2,500 cycles. If your application cycles this disconnector daily, factor that into your maintenance schedule.
