The Schneider Electric ENW24205 is an EasyPact NW switch disconnector rated 800 A in AC-23A duty at 690 V AC, 50/60 Hz, per IEC 60947-3. It's a 3-pole, fixed-mount unit with rear connection, IP40 finger-safe enclosure, and a rated impulse withstand voltage of 12 kV.
AC-23A covers occasional switching of individual motors with high starting currents — think compressors, pumps, conveyors. Below that, the short-time withstand current (Icw) is 66 kA for 1 s and 36 kA for 3 s, and the short-circuit making capacity (Icm) is 143 kA peak at 50/60 Hz. Those numbers tell you the switch can close onto a fault and hold through a downstream breaker's clearing time — critical for selectivity in a distribution board. Pollution degree 4 per IEC 60664-1 means the part is rated for harsh environments — conductive dust or condensation — so it's at home in industrial enclosures, not just clean switchrooms. The continuous duty rating means it can carry its rated current indefinitely without derating, as long as ambient stays within -5 to 70 °C.
Fixed base-plate mount, rear connection with a 115 mm pitch without spreader. The dimensions — 422 mm wide, 352 mm high, 297 mm deep — mean it needs a decent-sized enclosure; plan for a cabinet depth of at least 350 mm to allow cable bending radius behind the rear terminals.
