The drawout mounting lets you rack the breaker out for maintenance or replacement without pulling the bus bars, which saves hours of downtime on a live panel. The 1000 V rated insulation voltage (Ui) and 690 V operational voltage (Ue) cover common low-voltage distribution voltages up to 690 V line-to-line. ## Integration into the switchboard Drawout mounting on rails — the breaker slides into a cradle with rear horizontal or vertical connections. The 4-pole configuration (4P 4d) with neutral on the left means it can be set for 3D (no neutral protection), 3D + N/2 (half-rated neutral), or 4D (full neutral protection). Connection pitch is 115 mm without a spreader. The IP40 enclosure protection keeps fingers and tools out but is not sealed against water — install in a dry indoor switchboard. Dimensions: 556 mm wide, 439 mm high, 395 mm deep — plan the cubicle depth accordingly.","metaTitle":"ENW24154 EasyPact NW Circuit Breaker, 2500 A, 66 kA","metaDescription":"ENW24154 EasyPact NW drawout circuit breaker. 2500 A rated current, 66 kA breaking capacity at 440 V, IEC 60947-2.
