Switch disconnector for distribution, 2000 A AC-23A duty
The Schneider Electric ENW24209 is an EasyPact NW switch disconnector rated for 2000 A in AC-23A utilisation category at 690 V AC 50/60 Hz, covering motor switching with occasional inrush and distribution isolation. Three poles, fixed mounting on a base plate, rear connection vertical or horizontal. Suitability for isolation confirmed per IEC 60947-3, with a visible contact position indicator for positive open-gap verification during lockout-tagout.
Withstand and making capacity for fault coordination
Rated short-time withstand current (Icw) is 66 kA for 1 s or 36 kA for 3 s at -5 to 70 °C, per IEC 60947-3. Short-circuit making capacity (Icm) is 143 kA AC. These figures define the switch's ability to hold closed through a downstream fault and to close onto a fault without welding — critical for selectivity studies and SCCR compliance in distribution panels. Rated impulse withstand voltage (Uimp) of 12 kV and pollution degree 4 per IEC 60664-1 confirm suitability for harsh industrial environments with conductive contamination.
Active production, sourced to order
The ENW24209 carries an active lifecycle status from Schneider Electric. No end-of-life notice or successor part is recorded.
Mechanical and electrical endurance, service conditions
Mechanical durability is 20,000 cycles with maintenance or 10,000 without, per IEC 60947-3. Electrical durability in AC-23A: 6,000 cycles at 440 V and 4,000 cycles at 690 V without maintenance. IP40 protection means the enclosure resists tools and wires over 1 mm — suitable for indoor switchboards, not washdown zones. Connection pitch is 115 mm without spreader; the fixed mounting on a base plate suits panel layouts where DIN-rail isn't an option.
