Product details

The Schneider Electric EZC400H3400N is a 3-pole EasyPact EZC400H molded case circuit breaker rated 400 A at 40 °C, with a TM-D thermal-magnetic trip unit. The 50 kA Icu breaking capacity at 380 V AC (50/60 Hz) per IEC 60947-2 means it safely interrupts fault currents up to that level without upstream cascading — sized for distribution panels where available fault current is in that range. The 4000 A magnetic trip setting (10× In) handles motor inrush without nuisance tripping on Category A utilization.

Integration and deployment

Fixed backplate mounting with front-front connections (upside and downside). The 140 mm width and 45 mm pole pitch fit standard panel layouts. IP20 finger-safe terminals and IK07 impact resistance suit enclosed distribution boards.

Certified to EN/IEC 60947-2, JIS C8201-2-2, and GB/T 14048.2. Positive contact indication and toggle control provide clear visual status. No earth-leakage protection built in — specify an external Vigi module if needed.
