The Schneider Electric ENW24200 is an EasyPact NW switch disconnector rated for 1600 A in AC-23A duty at 690 V AC, meaning it handles heavy motor loads and mixed inductive-resistive switching where high inrush currents are expected. The 3-pole drawout design isolates the main contacts from the bus for maintenance access without de-energizing the entire switchboard — a standard requirement for distribution panels where uptime matters.
The 1600 A rating in AC-23A (IEC 60947-3) is the key selection figure — it is the current the switch can make and break for motor and mixed loads, not just resistive. The AC-23A category covers occasional switching of motors and other highly inductive loads, so this part is sized for a main incoming or feeder disconnector on a 690 V distribution board serving motor control centers. Short-time withstand (Icw) is 66 kA for 1 s and 36 kA for 3 s, which governs selectivity with downstream breakers — the switch must hold closed during a fault long enough for the nearest upstream breaker to clear. The making capacity (Icm) of 143 kA peak confirms it can close onto a bolted fault without welding contacts. Rated insulation voltage (Ui) is 1000 V AC, and impulse withstand (Uimp) is 12 kV — both exceed the 690 V operating voltage, giving margin for transient overvoltages common in industrial networks. The drawout mechanism (mounting mode: drawout) allows the switch to be racked out for isolation without unbolting cables — a time-saver during panel maintenance. Rear connection with a 115 mm pitch without spreader matches standard busbar layouts. Electrical durability is 6000 cycles at 440 V and 4000 cycles at 690 V in AC-23A without maintenance — enough for daily switching over a 10–15 year panel life. Mechanical durability is 20000 cycles with maintenance, 10000 without. The contact position indicator gives visual confirmation of open/closed state, required for lockout/tagout procedures.
