It's built for distribution duty in fixed-mount backplate panels, front-connected both line and load sides. The 50 kA Icu at 380 V AC (and 50 kA at 400/415 V AC, 70 kA at 220/230 V AC) gives you solid SCCR headroom for most industrial feeder circuits. Magnetic trip fires at 4000 A, so it clears hard faults fast without waiting for the thermal bimetal. The 400 A frame with a 320 A trip unit means you can feed a 320 A continuous load and still have the 400 A frame's thermal capacity for short-duration overloads. Serviceability (Ics) isn't listed here, so for repeated close-in faults you'd want to check the coordination study. IP20 finger-safe terminals keep live parts covered inside the enclosure. IK07 impact resistance and IP20 ingress protection. No earth-leakage protection built in — that's a separate accessory if you need it.","metaTitle":"Schneider Electric EZC400H3320N EasyPact EZC400H 3P 400A Cir","metaDescription":"Schneider Electric EZC400H3320N EasyPact EZC400H 3P 400A molded case circuit breaker. 50 kA Icu at 380 V AC, TM-D thermal-magnetic trip unit.
