The Schneider Electric EZC250H2100 is a 2-pole EasyPact EZC250H moulded-case circuit breaker rated 100 A at 40 °C, with a TM-D thermal-magnetic trip unit. The 100 A rating at 50 °C tells you the breaker holds full load at elevated panel temps — useful if the enclosure runs hot. Breaking capacity spans 10 kA Icu at 550 V AC up to 85 kA Icu at 240 V AC; the 36 kA Icu at 400-415 V AC is the figure most European distribution boards care about. For DC circuits, it delivers 30 kA Icu at 125 V DC (1P) or 250 V DC (2P). The 690 V AC rated insulation voltage and 550 V AC operational voltage cover standard 400/480 V systems with headroom. The breaker is Category A — no intentional short-time delay, so it trips instantaneously on fault. That makes it a good fit for feeder or branch protection where you want fast clearing, not selective coordination downstream. The toggle control gives positive contact indication: you see the position, no guessing. IP20 finger-safe terminals and IK07 impact resistance suit it for enclosed panel mounting on a backplate.
Certified to GB/T 14048.2, EN/IEC 60947-1, and EN/IEC 60947-2 — the core MCCB standards for China and Europe. No earth-leakage protection built in; if you need that, you'd add a separate RCD or use an EasyPact CVS with Vigi module.
