description: The subject of the graduate qualification work is "Modernization of contact current-carrying system of the NS160N low-voltage circuit breaker and electromagnetic release unit". This work is dedicated to the research of thermal condition of contact and current-carrying system of the Compact NS160N circuit-breaker, as well as the modeling of the magnetic tripping device which is connected to circuit-breakers of the Compact NS series. The tasks that were solved during the work are: Analysis of modern theory and practice in the study of heat-exchange processes in contact and current-carrying systems of low-voltage electrical apparatus. Development of a mathematical model of the thermal state of the Compact NS160N circuit breaker contact and current-carrying system. Development of a mathematical model of the magnetic release. Performing of numerical simulation and the analysis of its results. As a result, a mathematical model of the contact and current-carrying system was developed in COMSOL Multiphysics, and mechanical, electrical, and thermal calculations of this system were performed by numerical simulation. In addition, a model of the magnetic release was created in COMSOL Multiphysics.
