The Schneider Electric EZC100H3075 is a 3-pole EasyPact EZC100H molded case circuit breaker rated at 75 A (In) at 40 °C, with a TM-D thermal-magnetic trip unit. It carries a 10 kA Icu at 125 V DC (1P) and 250 V DC (2P), and on AC it delivers 100 kA Icu at 110-130 V / 220-240 V, 30 kA at 380-415 V, 20 kA at 440 V, and 10 kA at 550 V — all per IEC 60947-2. That's a wide fault-clearing envelope that covers most industrial distribution panels fed from a transformer of 500 kVA or less.
What the breaking capacity means on your line
The 30 kA at 400-415 V is the more common ceiling for European 400 V distribution. At 440 V it drops to 20 kA, still enough for most downstream feeders. On the DC side, 10 kA at 250 V (2P) covers battery banks and UPS outputs. The Category A utilization rating means this breaker is not intended for motor starting duty — it's a distribution breaker, not a motor circuit protector.
Backplate-mounted, fixed position. Front-facing connections top and bottom with a 25 mm connection pitch — standard for panel builder bus bar work. The toggle handle gives positive contact indication, so you can see the contact state at a glance. IP20 finger-safe protection on the front; IK07 impact rating means it'll survive a dropped tool in the panel.
Designed and tested to GB/T 14048.2, JIS C8201-2-2, EN/IEC 60947-2, and EN/IEC 60947-1. No earth-leakage protection built in; if you need RCD functionality, you add an external Vigi module upstream.
