The Schneider Electric ENW24196 is a fixed-mount switch disconnector in the EasyPact NW range, rated 4000 A in AC-23A duty at 690 V AC — that means it handles heavy motor loads and mixed inductive/resistive circuits where the switching frequency is moderate but the fault current potential is high. Four poles, neutral on the left, rear vertical/horizontal connection with a 115 mm pitch without spreader. It's built for distribution panels and main incomer positions where you need a single disconnect that can make and break fault currents up to 121 kA peak and withstand 55 kA for 1 second.
Ratings that matter for the panel designer
The AC-23A utilisation category is the key: it covers switching of motors and other highly inductive loads, and the 4000 A rating at 690 V is the operational current for that duty. Short-time withstand (Icw) is 55 kA for 1 second or 30 kA for 3 seconds — this tells you the disconnector can hold closed under fault current long enough for an upstream breaker to clear, which is critical for selective coordination in a distribution board.
Electrical durability under AC-23A is 5,000 cycles at 440 V and 2,500 cycles at 690 V without maintenance. Ambient operating range is -5 to 70 °C; storage goes from -40 to 85 °C.
Designed and tested to IEC 60947-3 for switch-disconnectors, with a suitability-for-isolation marking. Rated impulse withstand voltage (Uimp) is 12 kV.
