I can see how it's possible to choose definitions so that your viewpoint is valid. But I think the common definition of "limit current" in this context disagrees with you.
The function of a circuit breaker is to
interrupt the current, not to limit it. A 20 amp fuse or circuit breaker does not limit the current to 20 amps. If you try to draw more than 20 amps for long enough to trip the breaker, the current is
stopped. That's not what current limiting means in my book.
