The thermal-magnetic trip unit handles overloads and short circuits up to 6 kA Icn at 400 V AC (EN/IEC 60898-1) or 10 kA Icu at 400...415 V AC (IEC 60947-2), so the same breaker covers both domestic and industrial coordination requirements depending on which standard the panel designer follows.
The C curve (magnetic trip 5...10 x In) means this breaker tolerates moderate inrush without nuisance tripping — suited for lighting banks, small transformers, or motor circuits where the start-up surge falls within that multiple. The 10 A rating is the continuous thermal current; load current should not exceed it for sustained periods. For panels requiring 10 kA SCCR at the branch, this MCB meets it under the 60947-2 rating.
Deployment context
Tropicalisation level 2 per IEC 60068-1 means it handles 95 % RH at 55 °C, so it can serve in non-air-conditioned electrical rooms in humid climates.
