Over here in Germany we call the breakers Leitungsschutzschalter, which translates to wiring protection switch. They're specifically sized to protect the wiring in an overload situation, both gradual overloads and short circuits.
The main issue is actually with the slightly-less trigger-happy breakers (class D) needing a sufficiently low resistance on the output to ensure that the magnetic trigger is both reliably triggered if you short the outlet, yet reliably not triggered by the current spike allowed from it's class. They trigger between 10 and 20 times the nominal rating, and 16 A is the typical circuit choice here. Ensuring that you reliably hit 320 A through a long circuit isn't the easiest/cheapest thing.

C/D are more appropriate for industrial use, where wiring and devices are designed beforehand, and people (ideally) won't just join together extension cords, and put multiple electric motors on it.
