It breaks 36 kA Icu at 380/415 V AC per IEC 60947-2, which is the typical line-to-line voltage in European 400 V distribution panels — so it handles fault currents up to that level without upstream fuses needing to open first. The 4-pole construction (3 phases + neutral) with neutral protection set to 3D (no protection) suits it for 3-phase, 4-wire systems where the neutral is a distributed conductor but not separately protected.
Breaking capacity — what the F code means for your panel
At 220/240 V AC it rises to 85 kA Icu; at 690 V AC it drops to 8 kA Icu. For a 400 V distribution board with a transformer of 1.5–2 MVA, 36 kA is typical for main or sub-main breakers. The C10F6TM080C is utilisation category A, meaning it is not intended for motor starting duty (no frequent on-off switching under load).
