The article deals with the issue of determining the regularity of the selection of selective switches. To solve this problem, the object of research is single-module automatic breakers with different characteristics and numbers, which are installed on a DIN Rail. The results of the work allow us to make such a selection of automatic breakers that can ensure guaranteed disconnection of the automatic breaker of the head section when an overcurrent flows through one of the branches, as is also identify a damaged branch of the distribution network.
