Breaking capacity is 10 kA per EN 60898 and 15 kA per IEC 60947-2 at 400 V AC — the higher figure applies when the breaker is used in industrial applications where the standard allows the full IEC rating. That 15 kA ceiling gives headroom for high-fault panels without cascading upstream.
Rated voltage is 400 V AC; DC rated voltage is 60 V.
