The Schneider Electric ENW24280 is a 1600 A switch disconnector from the EasyPact NW range, built for distribution duty and rated for isolation per IEC 60947-3. It switches 1600 A continuously in AC-23A utilisation category at 690 V AC, meaning it handles motor loads with occasional switching — not just resistive heater banks — and provides visible isolation for safe maintenance access. The 4-pole configuration with neutral on the right matches standard panel layouts for three-phase plus neutral distribution.
The 1600 A rating is the operational current in AC-23A duty at 690 V — the category for motors, transformers, and inductive loads where making and breaking currents are higher than resistive switching. The short-time withstand current (Icw) is 66 kA for 1 second and 36 kA for 3 seconds, which tells you the switch can ride through a fault long enough for an upstream breaker to clear — critical for selective coordination in a distribution panel. The short-circuit making capacity (Icm) of 143 kA at 50/60 Hz means it can close onto a fault without welding contacts.
Drawout mounting on a rail — the switch pulls out for inspection or replacement without disturbing the main bus connections. Rear connection with vertical or horizontal orientation; the 115 mm connection pitch without spreader matches standard busbar drilling. The IP40 enclosure keeps tools and fingers out but is not washdown-rated — install in a cabinet, not in a wet area. The contact position indicator gives a visual open/closed status, which speeds up LOTO verification during maintenance rounds.
