Selectivity between the circuit breaker on the pole and in the house

Paul asks:
Is it possible to put a circuit breaker with the same ampere rating as at the input (pole) at home, but at the same time it should operate earlier at home? On the pole there is a 10 amp shield.
The answer to the question:
10 amperes? 3 phases probably? An interesting quantity. Can. In order for the time-current characteristic to be triggered at the machine in the home electrical switchboard earlier, it should be more sensitive than on the support. That is, if it is supported by C10, then B10 should be in the house. But this does not give a 100% guarantee that the house will work faster. Both machines will continue to operate on currents up to 11.3 Amps.
