The drawout mounting means the breaker chassis slides out of its cradle for inspection or replacement without disturbing the bus connections, which cuts downtime on a line-down event. Breaking capacity is 66 kA Icu at 220…440 V AC and 50 kA Icu at 690 V AC, both per IEC 60947-2. The Ics (service breaking capacity) is 65 kA at 440 V, meaning it can clear that fault level repeatedly without needing replacement, which matters for coordination studies. ## Pollution degree 4 — what it changes Rated pollution degree 4 per IEC 60664-1 means the breaker is designed for environments where conductive pollution (dust, moisture, condensation) is present and the insulation system must tolerate continuous exposure. This is the standard rating for open-air switchgear in industrial halls — not a clean-room or climate-controlled panel. The IP40 enclosure (finger-safe, no water protection) is consistent with indoor switchgear installation; if the board is in a washdown area, you need an outer enclosure. ## Integration into the switchboard Mounting is drawout on a rail support, with rear vertical/horizontal connection positions. The neutral sits on the left side (4P 4d protected poles). Connection pitch is 115 mm without a spreader — that dimension governs busbar drilling and busway alignment in the switchgear. Dimensions: 556 mm wide, 439 mm high, 395 mm deep.","metaTitle":"Schneider Electric ENW24155 EasyPact NW Circuit Breaker, 320","metaDescription":"ENW24155 EasyPact NW drawout circuit breaker, 3200 A rated at 40 °C, 66 kA Icu at 440 V.
