The 36 kA Icu at 440 V AC (40 kA at 220/230 V) tells you it safely interrupts fault currents up to that level without welding or rupturing — that is the interrupting rating, not the continuous load. For a distribution panel feeding a 400 A bus, this breaker clears a bolted fault before upstream gear has to act. The magnetic trip is fixed at 3200 A, so it handles motor inrush without nuisance tripping on loads up to about 800 A starting current. Mounts fixed to a backplate with front-front connections — no DIN-rail clip here, so plan for bolt-down integration in the enclosure. IP20 finger-safe terminals and IK07 impact resistance mean it is suited for a standard industrial panel, not a washdown zone. The toggle control and positive contact indication give a clear visual of breaker state without opening the door. Compliance documentation covers the usual industrial baselines: the breaker is designed to EN/IEC 60947-2 and EN/IEC 60947-1, with GB/T 14048.2 and JIS C8201-2-2 as additional standards. No RoHS or REACH statement is in the evidence, but the IEC 60947-2 listing implies the standard material declarations for this class. ## Integration notes Fixed mounting on a backplate, 45 mm pole pitch. Electrical durability is 4000 cycles at 415 V AC, mechanical durability 10,000 cycles. For a main distribution breaker that cycles infrequently (once a month for maintenance isolation), that is effectively lifetime duty.","metaTitle":"Schneider Electric EZC400N3350N EasyPact EZC400N 3P 400A, 36","metaDescription":"Schneider Electric EZC400N3350N EasyPact EZC400N molded case circuit breaker, 3-pole, 400 A rated current, 36 kA breaking capacity at 440 V AC, TM-D trip unit.
