The Schneider Electric ENW24194 is an EasyPact NW switch disconnector rated for 2500 A in AC-23A duty at 690 V AC, 50/60 Hz, with four poles.
The AC-23A utilisation category covers switching of motor loads and other highly inductive loads — the 2500 A rating is the operational current at 690 V for that duty, not a resistive-heater rating. For short-circuit conditions, the switch can make onto 105 kA peak (Icm) and withstand 50 kA for 1 second (Icw), which gives the panel designer headroom for high-fault installations. Pollution degree 4 per IEC 60664-1 means the switch is rated for harsh environments where conductive pollution (dust, moisture) may occur — typical in heavy industrial switchrooms or outdoor enclosures. The IP40 enclosure rating keeps tools and fingers out but is not washdown-rated; install it inside a panel if the ambient is wet.
