The Schneider Electric EZC250N4100 is a 4-pole EasyPact EZC250N circuit breaker with a fixed thermal-magnetic TM-D trip unit rated 100 A at 40 °C (100 A at 50 °C). The N breaking capacity code means it delivers 20 kA Icu at 440 V AC 50/60 Hz, with higher ratings at lower voltages: 50 kA Icu at 220...240 V AC and 25 kA Icu at 380...415 V AC. For DC circuits, it offers 20 kA Icu at 125 V DC (1P) and 20 kA Icu at 250 V DC (2P). This makes it suitable for main or branch feeder protection where fault levels are moderate.
Mounts fixed to a backplate via the 35 mm connection pitch. Front-facing connections on both line and load sides simplify busbar or cable routing in a panel. The toggle handle provides positive contact indication — you can see the contact state without removing the cover. IP20 finger-safe protection on the front, IK07 impact resistance. Pollution degree 3 per IEC 60947 means it tolerates conductive pollution in industrial environments.
