Switch disconnector for distribution duty — 1600 A, AC-23A
The Schneider Electric ENW24288 is a 4-pole switch disconnector from the EasyPact NW range, rated 1600 A in utilisation category AC-23A at 690 V AC. That AC-23A rating means it handles mixed motor and resistive loads with frequent switching — 6000 cycles at 440 V, 4000 cycles at 690 V without maintenance, per IEC 60947-3. It is also certified for isolation (suitability for isolation conforming to IEC 60947-3) with a visible contact position indicator, so it doubles as a service-disconnect for a panel or machine. Rated insulation voltage is 1000 V AC, impulse withstand 12 kV, and short-time withstand current hits 66 kA for 1 s or 36 kA for 3 s. Short-circuit making capacity is 143 kA at 50/60 Hz — numbers that place it in heavy industrial distribution, not light commercial. Pollution degree 4 (IEC 60664-1) confirms it tolerates conductive dust or condensation, typical in unsealed switchrooms.
Fixed base-plate mount, rear connection, neutral on the right. Dimensions: 537 mm wide, 352 mm high, 297 mm deep. Connection pitch is 115 mm without spreader. IP40 enclosure protection — no washdown rating, but fine for indoor switchgear.
