The Schneider Electric ENW24173 is a fixed-mount switch disconnector from the EasyPact NW range, rated for 800 A in AC-23A duty at 690 V AC, 50/60 Hz.
The short-time withstand current (Icw) is 50 kA for 1 second or 25 kA for 3 seconds, which governs selectivity coordination: downstream devices must clear a fault before this switch disconnector's thermal limit is reached. The short-circuit making capacity (Icm) is 105 kA peak, confirming it can close onto a bolted fault without welding contacts. Pollution degree 4 per IEC 60664-1 is the most severe industrial classification — conductive dust or condensation is expected. Suitability for isolation is marked Yes per IEC 60947-3, so the open position provides a visible air gap that satisfies lockout/tagout requirements.
Deployment context
Fixed mounting on a base plate with rear connection terminals. The 422 mm width and 352 mm height fit a standard enclosure footprint; depth is 297 mm including the operator mechanism. Connection pitch is 115 mm without spreader — verify busbar or cable lug spacing against your existing assembly. The contact position indicator gives a visual open/closed confirmation at the front of the switch.
