MCCB for distribution panels — 160 A, 4-pole, thermal-magnetic
The Schneider Electric EasyPact EZC250N44160 is a 4-pole MCCB rated 160 A at 40 °C (trip unit TM-D, 160 A at 50 °C) for distribution duty in commercial and industrial panels. Its 20 kA Icu at 440 V AC (IEC 60947-2) covers most building and light industrial fault levels; the same breaker delivers 50 kA Icu at 240 V AC and 25 kA at 380–415 V AC. The thermal-magnetic trip handles overload and short-circuit protection — no earth-leakage module on this variant. Pollution degree 3 and IP20 enclosure make it a standard fit for enclosed switchboards.
The N breaking-capacity code (20 kA Icu at 440 V AC) is the mid-range option in the EZC250 family. For the same frame size, the H code steps up to 36 kA Icu at 440 V AC — worth considering if the fault level at the panel exceeds 20 kA. At 380–415 V AC this breaker holds 25 kA Icu, so it coordinates with most upstream 25 kA or 36 kA molded-case breakers in a standard distribution hierarchy.
Fixed mount on a backplate (screw-mount, not DIN rail). Dimensions 165 mm high × 140 mm wide × 60 mm deep. Connection pitch 35 mm. Toggle handle with positive contact indication — no rotary handle on this variant. IP20 finger-safe terminals; IK07 impact rating for the enclosure.
