The Schneider Electric ENW24228 is a 4000 A switch disconnector from the EasyPact NW range, built for distribution duty in fixed-mount, 4-pole configuration. It is rated AC-23A at 690 V — that is the heavy motor-and-mixed-load category per IEC 60947-3, meaning it handles the high inrush of switching motors, transformers, and inductive loads on a distribution bus, not just resistive heating. Rated operational current is 4000 A AC at 690 V 50/60 Hz, with a short-time withstand (Icw) of 66 kA for 1 s and a making capacity (Icm) of 143 kA AC — numbers that tell you this part is sized for main incoming or large feeder isolation where fault levels are high. The insulation voltage (Ui) is 1000 V AC, and impulse withstand (Uimp) is 12 kV, so it holds up in industrial environments with voltage transients. The IP40 enclosure keeps out tools and wires over 1 mm but is not sealed against water; install in a cabinet or switchgear lineup.
Electrical durability for AC-23A is 5000 cycles at 440 V and 2500 cycles at 690 V without maintenance — so if you are cycling this daily under load, factor in the maintenance interval.
