The Schneider Electric ENW24174 is a fixed-mount switch disconnector from the EasyPact NW range, rated for 1000 A in AC-23A utilisation category at 690 V AC 50/60 Hz. It is a 3-pole device with rear connection, designed for distribution applications where load-break switching and visible isolation are required. The AC-23A rating means it handles occasional switching of motor loads or other highly inductive circuits — not just resistive loads — so it suits mixed-load panels where a general-purpose disconnect is needed rather than a dedicated motor-circuit switch.
Rated operational current (Ie) is 1000 A in AC-23A at 690 V. Rated insulation voltage (Ui) is 1000 V AC, and rated impulse withstand (Uimp) is 12 kV per IEC 60947-3. These tell you the switch is designed for 690 V systems with adequate clearance for surge events up to 12 kV — typical for industrial distribution where the supply transformer and upstream protection set the coordination level. Short-time withstand (Icw) is 50 kA for 1 second or 25 kA for 3 seconds. Short-circuit making capacity (Icm) is 105 kA peak at 50/60 Hz. These numbers define the switch's ability to survive a fault and close onto a short circuit — critical for selectivity studies and SCCR compliance in the panel schedule. Pollution degree 4 per IEC 60664-1 means the switch is rated for harsh environments where conductive pollution (dust, moisture, carbon deposits) is present — typical of heavy industrial or outdoor enclosures.
