The Schneider Electric ENW24283 is a 4-pole switch disconnector from the EasyPact NW range, rated for 3200 A in AC-23A utilisation category at 690 V AC. AC-23A covers switching of motor loads and other highly inductive loads — this is not a general-purpose disconnect; it is sized for heavy motor circuits or large distribution feeders where frequent on-load switching is expected. Rated short-time withstand current (Icw) is 66 kA for 1 s, and short-circuit making capacity (Icm) is 143 kA peak. These numbers define the fault-handling capability: the switch can close onto a fault up to 143 kA peak and hold 66 kA rms for one second without welding or damage. That puts it in the HA breaking capacity class — suitable for high-fault-current installations where upstream protection coordinates with this rating. Rated insulation voltage (Ui) is 1000 V AC, and impulse withstand (Uimp) is 12 kV, confirming it is suitable for isolation per IEC 60947-3. Pollution degree 4 (IEC 60664-1) means it tolerates conductive dust or heavy condensation — typical in industrial switchrooms, not clean conditioned spaces.
Drawout mounting on a rail with rear connection. The 115 mm connection pitch (without spreader) and right-side neutral position are fixed — panel layout must accommodate these. Horizontal or vertical connection orientation is possible. IP40 enclosure protection means it is suited for indoor switchgear assemblies, not washdown or outdoor locations. Electrical durability for AC-23A duty is 5,000 cycles at 440 V and 2,500 cycles at 690 V. These are the maintenance-interval triggers: at 690 V motor switching, plan inspection around 2,500 operations.
