Product details

The Schneider Electric EZC400H44350N is a 4-pole EasyPact EZC400H molded case circuit breaker rated 400 A at 40 °C, with a TM-D thermal-magnetic trip unit set for 350 A at 50 °C. The 3500 A magnetic trip threshold clears bolted faults fast, while the thermal element handles overloads. IP20 finger-safe terminals and IK07 impact resistance keep the panel side safe during commissioning. It ships as a single piece with front-front connections (line and load both front-facing), fixed backplate mounting, and a toggle handle with positive contact indication — no loose accessories to chase. The 140 mm width × 255 mm height × 140 mm depth footprint fits standard distribution panel cutouts; the 45 mm pole pitch matches busbar systems common in IEC switchgear. No earth-leakage module is integrated, so if you need ground-fault protection, plan an external relay and toroid downstream.
