The 66 kA Icu at 220…440 V AC (IEC 60947-2) means it can safely interrupt fault currents up to that level without failing — critical for high-fault-capacity switchboards where upstream coordination depends on the breaker clearing a short circuit within 25 ms maximum breaking time. The 65 kA Ics (service breaking capacity) at the same voltage tells you it can reclose after a fault without immediate maintenance, which matters for continuous-process lines where a single fault shouldn't force a shutdown for inspection. Rated insulation voltage is 1000 V AC, and operational voltage goes to 690 V AC. The 4-pole design (4 protected poles) with neutral on the left supports both 3D and 4D configurations; neutral protection can be set to 0.5 x Ir or 1 x Ir, or left unprotected. Drawout mounting on a rail with rear horizontal or vertical connections — the breaker chassis slides into a fixed cradle, so you can rack it out for maintenance or replacement without disturbing the bus bars. Dimensions: 556 mm wide, 439 mm high, 395 mm deep. Connection pitch is 115 mm without a spreader. IP40 enclosure protection keeps tools and fingers out but isn't rated for washdown; install in a clean, dry switchgear cubicle.","metaTitle":"Schneider Electric ENW24149 EasyPact NW Circuit Breaker, 800","metaDescription":"ENW24149 EasyPact NW air circuit breaker, 800 A rated at 40 °C, 66 kA Icu at 440 V AC.
