On the substitution of low-voltage electric apparatuses

A study was conducted, to provide additional data on the substitution of low-voltage electric apparatuses. It was found that these low-voltage electric apparatuses are substituted, with new low-voltage apparatuses for the distribution, protection, and control of circuits and electric drives that have higher characteristics of reliability, durability, and lower-size parameters. The study focused on gathering more data on the substitution of low-voltage electric apparatuses, as a lack of knowledge of the tables of substitutions results in the use of old and low-voltage electric apparatuses in new developments and designs. The lack of significant data on the substitution of these apparatuses also requires significant amount of time and financial resources for conducting irrelevant searches.
