It's a Category B breaker — meaning it's designed for distribution in industrial switchgear where selectivity and coordination with downstream devices matter. The drawout mounting lets you rack the breaker out for maintenance without disturbing the bus connections, which is standard for large low-voltage mains and tie feeders. At 690 V the Icu drops to 50 kA, which still covers most industrial 690 V distribution. The 25 ms maximum break time is fast enough to limit let-through energy for downstream coordination. ## Integration notes Mounts on a rail with drawout mechanism — rear horizontal or vertical connection positions, 115 mm connection pitch without spreader. IP40 enclosure protection; suitable for indoor switchgear cubicles. Control is push-button operated. Ambient operating range -5 to 60 °C; storage down to -40 °C without control unit. Mechanical durability: 20,000 cycles with maintenance, 10,000 without.","metaTitle":"Schneider Electric ENW24156 EasyPact NW Circuit Breaker, 400","metaDescription":"Schneider Electric ENW24156 EasyPact NW drawout circuit breaker, 4000 A rated current, 66 kA Icu at 440 V, IEC 60947-2.
