Product details

The Schneider Electric EZC400H3350 is a 3-pole EasyPact EZC400H molded case circuit breaker rated 400 A at 40 °C (In) with a TM-D thermal-magnetic trip unit. The TM-D trip unit provides both overload (thermal) and short-circuit (magnetic) protection in one package, with a magnetic trip threshold of 3200 A. Mounts fixed to a backplate (not DIN rail), so plan for a dedicated mounting surface in the enclosure. Front-connect terminals on both line and load sides simplify bus-bar or cable routing in a standard distribution panel layout.

Compliance documentation is available: the breaker carries IEC 60947-2, GB/T 14048.2, and JIS C8201-2-2 approvals, plus IP20 and IK07 mechanical impact protection.

Integration notes

Dimensions: 255 mm high, 140 mm wide, 140 mm deep. The 44 mm pole pitch matches standard bus-bar spacing for 3-pole breakers in this class. Mechanical durability is 10,000 cycles; electrical durability is 4,000 cycles at 415 V AC. That's typical for a distribution breaker — not intended for frequent switching duty like a contactor, but fine for isolation and backup protection in a fixed installation.
