The Schneider Electric EZC250N44200 is a 4-pole EasyPact EZC250N thermal-magnetic circuit breaker rated 200 A at 40 °C (200 A at 50 °C on the trip unit). It carries a 20 kA Icu at 440 V AC — the N breaking capacity code — and is certified to IEC 60947-2. The TM-D trip unit provides short-circuit and overload protection; there is no integral earth-leakage module. It ships as a fixed-mount, front-connect unit with a toggle handle and positive contact indication. The kit is complete: no missing brackets or separate trip units to order.
The 20 kA Icu at 440 V AC is the headline fault-interruption figure for a 200 A frame in a distribution panel. At 380–415 V AC it rises to 25 kA, and at 220–240 V AC it reaches 50 kA — useful for high-fault locations near a transformer. On DC, it manages 20 kA at 125 V (1-pole) or 250 V (2-pole). The 8 kA Icu at 550 V AC is the ceiling for the rated operational voltage. For a Category A breaker (no intentional short-time delay), selectivity with downstream devices depends on the instantaneous trip threshold of the TM-D unit.
Fixed backplate mount, 35 mm connection pitch, front terminals top and bottom. Dimensions: 165 mm high, 140 mm wide, 60 mm deep. IP20 finger-safe enclosure; IK07 impact resistance. No neutral protection fitted — the 4t protected poles cover all four phases, with the neutral unprotected.
