MCCB for distribution panels — 125 A, 4P, H breaking capacity
It carries a 125 A TM-D thermal-magnetic trip unit at 50 °C, with four poles (4P) and a neutral position on the left. The H breaking capacity code delivers 70 kA Icu at 415 V AC and 100 kA Icu at 240 V AC, per IEC 60947-2. At 690 V AC it still interrupts 10 kA — useful for industrial feeders where fault levels vary by voltage class. Rated for isolation (EN/IEC 60947-2), so it doubles as a visible-break disconnect in the panel without a separate switch.
The Icu curve is steep: 100 kA at 240 V, 70 kA at 415 V, 65 kA at 440 V, 50 kA at 500 V, 35 kA at 525 V, and 10 kA at 690 V. For a 480 V panel (common in North America), the 50 kA Icu at 500 V gives headroom above typical 25–35 kA available fault currents. No earth-leakage module is integrated — add a Vigi add-on block if ground-fault protection is required.
IP40 enclosure protection (IK07 impact) means it is suitable for indoor panel installation where tools are required to access live parts. The toggle control provides manual on/off and trip indication.
