description: This work is devoted to the study of the thermal state of the contact current-carrying system of the circuit breaker VANE-4000 for further modernization using mathematical modeling and numerical methods. The geometry of the existing contact system of the circuit breaker was taken as the basis. During the work, an analysis of modern theory and practice in the field of design of circuit breakers was made, a mathematical model was created and verified, based on full-scale tests, to evaluate the thermal state of the contact current-carrying circuit breaker system in the COMSOL Multiphysics software product. A parametric study of the contact current-carrying system was carried out at various ambient temperatures in a wide range of values from a number of nominal currents. As a result of the analysis of the results of numerical modeling, a modernization of the contact current-carrying system was proposed to increase the nominal current to 4 kA by increasing the radius of contact rounding.
