The C-curve trips magnetically between 5× and 10× rated current (50–100 A for this 10 A unit), which is the standard choice for general-purpose loads like small motors, transformers, and capacitor banks where the inrush peak is higher than resistive loads but still within the curve's window. The 7.5 kA rating is the short-circuit capacity at 415 V AC per EN 60898; the same breaker is also rated for DC operation up to 72 V, making it usable in DC sub-circuits within the same panel if the polarity and voltage stay within that limit.
The breaker accepts supplementary devices like auxiliary switches, shunt trips, and alarm contacts from the SENTRON accessory range.

Mounts in any orientation. The 10 000 mechanical operating cycles cover decades of normal switching in a residential or commercial panel.
