Do people take into account short-circuit current when choosing circuit breakers?

Thank you. When dealing with lighting power distribution, I only take the rated current into consideration; sometimes, when the distance is large, I also consider the voltage drop
Circuit breakers require short-circuit testing and sensitivity testing, both of which take short-circuit current into account
It must be taken into account, whether for existing production or new projects
Thank you. Do you use Tianzheng or manual calculation?

The new project design institute provides the short-circuit currents for the high-voltage and low-voltage systems. Once the system is put into operation and no expansion is carried out, the settings are generally based on the design provided by the institute; I carry out my calculations manually
