description: Topic of the thesis : modernization of the circuit breaker with nominal parameters of 400 V and 4000A. This work is devoted to research and modernization of contact system of low - voltage circuit breaker with nominal parameters 400Ð and 4000Ð. 1. Air switches 400Ð 2. Development of mathematical model of operation of circuit breaker 3. Numerical Simulation Results The work was carried out using the AutoCAD program, where the three - dimensional geometry of the contact system of the circuit breaker and COMCSOL Multiphysics was built, equipped with databases of the necessary parameters, where numerical simulations were carried out. As a result, a non - stationary mathematical model of the operation of a low - voltage circuit breaker was developed taking into account the mechanics of the switching process. Based on the existing prototype, the results of numerical modeling regarding the developed experimental study methodology are obtained. Also, the operation of the switch was modeled, the results of simulation of arc quenching were obtained, the results of modeling and data from experimental studies were compared.
