The 50 kA Icu breaking capacity holds at 380 V through 440 V AC — that's the same fault-interruption rating across the common industrial distribution voltages, so you don't lose headroom stepping from 400 V to 415 V. At 220–240 V it jumps to 70 kA Icu. The magnetic trip is fixed at 3200 A, meaning instantaneous protection kicks in at 8× In for short-circuit faults. This is a Category A breaker (no intentional short-time delay), suited for distribution duty where you need straightforward overload and short-circuit protection without selectivity coordination against downstream breakers. No earth-leakage protection built in, so if you need that, plan for an external Vigi module or separate RCD. Fixed-mount design for backplate installation — no DIN-rail adapter here. The 255 mm height × 140 mm width × 110 mm depth footprint fits standard distribution panel cutouts. IP20 finger-safe protection on the front, IK07 impact resistance for the enclosure face.","metaTitle":"Schneider Electric EZC400H3350N EasyPact EZC400H 3P 400A Cir","metaDescription":"Schneider Electric EZC400H3350N EasyPact EZC400H 3-pole circuit breaker, 400A rated at 40°C, 50kA breaking capacity at 380-440V AC.
