The Schneider Electric EZC630H44400N is an EasyPact EZC630H moulded-case circuit breaker (MCCB) rated 630 A at 40 °C, with 4 poles and a thermal-magnetic TM-D trip unit. It delivers 50 kA Icu at 380 V AC and 440 V AC (50/60 Hz) per IEC 60947-2, and 70 kA at 220/230 V AC. The H breaking capacity code places it in the high-interrupting tier for this frame size — suited for main distribution boards or large feeder circuits where fault currents can reach 50 kA at typical 400 V levels.
The TM-D trip unit provides short-circuit (magnetic) protection at a fixed 3500 A and overload (thermal) protection adjustable via the rating plug — the unit is rated 400 A at 50 °C, meaning the thermal calibration shifts with ambient.
Fixed-mount with front-connect terminals on a 45 mm pole pitch. The backplate mounting and 185 mm width mean it occupies a standard MCCB footprint in a panel — no DIN-rail clip, so plan for bolted busbar or lug connections. IP20 finger protection and IK07 impact resistance are typical for enclosed distribution boards; the breaker itself is not rated for washdown environments.
