Its C tripping characteristic handles inrush currents from motor starters and contactor coils without nuisance trips, while the 10 kA breaking capacity per EN 60898 (15 kA per IEC 60947-2) covers most secondary distribution faults in a 400 V AC panel.
Rated at 400 V AC and 60 V DC. C-curve magnetic trip at 5–10× In. The IP20 body (IP40 at the handle) is standard for a DIN-rail device; it expects to live inside a cabinet, not on the open floor. The 95 % humidity limit without condensation is typical for MCBs; no derating curve is published in these specs, so treat the 75 °C ceiling as the absolute max for the enclosure ambient.
What the approvals tell you
The pollution degree 3 and overvoltage cat III ratings align with IEC 60947-1 and -2. No UL/CSA listing is stated in the evidence, so for North American panels verify the specific UL 489 or CSA C22.2 file if required by local code.
