Calculation of electrodynamic forces acting on current path of 160 A circuit breaker

This work deals with the calculation of forces acting on a current carrying path breakers, namely op type BC160 fy Letohrad. There is described the principle of electrodynamic forces and calculation of these forces for different current carrying path. Finally, a simplified model is created by using a circuit breaker simulation program and then forces that arise during the passage of a current are calculated
