The Schneider Electric ENW24128 is a fixed-mount EasyPact NW circuit breaker rated 1600 A at 40 °C, with a breaking capacity of 50 kA Icu at 220...440 V AC 50/60 Hz per IEC 60947-2. It is a 4-pole device (4P 4d) with rear vertical/horizontal connections and a 115 mm connection pitch without spreader. The IP40 enclosure suits indoor distribution panels where dust and accidental contact are the main concerns — not washdown or outdoor exposure.
Pollution degree 4 per IEC 60664-1 means the internal clearances are designed for conductive dust or heavy condensation environments — a step above the usual PD3 found in commercial gear.
Deployment context
This breaker mounts fixed to a base plate (not DIN rail) with rear connections — typical for large low-voltage switchboards in industrial or utility distribution. The 537 mm width, 352 mm height, and 297 mm depth require a dedicated compartment; plan for busbar and cable entry clearance on the rear side. The push-button control type means manual open/close on the front face, with a contact position indicator for visual status.
