The Schneider Electric ENW24181 is a 4-pole switch disconnector from the EasyPact NW range, rated 800 A in AC-23A utilisation category at 690 V AC — meaning it handles motor switching and mixed resistive-inductive loads with frequent making and breaking, not just isolation. It is certified to IEC 60947-3 and carries a suitability-for-isolation marking, so it doubles as a visible-break disconnect for lockout-tagout procedures. Rated short-time withstand current (Icw) is 50 kA for 1 s or 25 kA for 3 s, and short-circuit making capacity (Icm) hits 105 kA peak — figures that matter for coordination with upstream protection and for verifying the switch can close onto a fault without welding contacts.
Drawout (withdrawal) mounting on a rail — the switch chassis slides out for inspection or replacement without disturbing the fixed rear connections. Connection pitch is 115 mm without spreader, neutral on the left, and rear connection location suits panel layouts where front access is limited. IP40 enclosure protection keeps tools and fingers out but is not rated for washdown — install inside a cabinet or switchgear cubicle. Dimensions: 556 mm wide, 439 mm high, 395 mm deep — verify cutout and swing-clear space before panel layout.
Durability and operating conditions
Mechanical durability: 20,000 cycles with maintenance, 10,000 without. Electrical durability at AC-23A: 6,000 cycles at 440 V, 4,000 cycles at 690 V. These numbers drive the preventive replacement interval in high-cycle applications like crane or conveyor disconnects. Continuous rated duty — no derating needed for sustained load.
