We have made an investigaton of basic characteristics of electromagnetic circuit braker using numerical simulation. We developed a model for numerical simulation of magnetic field for the case of axial simetry and AC signal biasing. An appropriate mathematical description of phenomena was set and appropriate software for solving the problem was used. The results present distributtion of magnetic field inside the parts of electromagnetic circuit braker. Based on numerical simulation we have drawn conclusions that served for optimization of the device and its parts.

Using software tools from the company Bober INŽENIRING we have done 3d simulation of an electromagnetic circuit braker with a short circuit ring. Simulations have revealed that a short circuit ring improves the behavior of the device. Numerical simulation has been used for optimization of design parameters that has enabled a reduction of a vibration of a moving contact at overloads. The results of numerical simulations have been compared with the ones from the developed device.
