The Schneider Electric ENW24223 is a fixed-mount switch disconnector from the EasyPact NW range, rated 1250 A in AC-23A duty at 690 V AC. The 4-pole configuration with neutral on the left suits distribution panels where a single disconnect isolates all conductors. The HA breaking capacity code means it handles high prospective fault levels — backed by a 66 kA short-time withstand (Icw) for 1 second and a 143 kA making capacity (Icm). It is certified as an isolator per IEC 60947-3, so it provides visible-break isolation for downstream maintenance.
The AC-23A utilisation category covers switching of motor loads and other highly inductive circuits — this is not a general-purpose resistive load switch. At 690 V AC the rated operational current is 1250 A; the electrical endurance is 6000 cycles at 440 V and 4000 cycles at 690 V without maintenance. Mechanical durability is 20000 cycles with maintenance, 10000 without. The rated insulation voltage (Ui) is 1000 V AC, impulse withstand (Uimp) is 12 kV, and pollution degree 4 per IEC 60664-1 means it tolerates conductive dust environments — often found in cement, mining, or heavy industrial panels.
Fixed base-plate mount, rear connection with a 115 mm connection pitch (without spreader). The 537 mm width and 352 mm height fit standard distribution cubicle compartments; depth is 297 mm. IP40 front protection means it is suited for indoor panel installation where tools are required to access live parts.
