Mechatronic approach is the most appropriate one for all multidisciplinary systems, involving different physical phenomena. In low voltage switching devices, the dynamic behavior of the electric and mechanical subsystems is strongly correlated with arc discharges taking place in vacuum (10⁻⁷ ...10⁻¹⁰ bar). In order to preserve the safety operation of all the consumers of a power supply, the discharges must extinguish at the first passing through zero of the current. The existence od axial or/and radial magnetic field can improve the behavior of the discharge. By modeling the electromagnetic field in the vacuum chamber and the phenomena within the plasma column between the two contact parts, the authors want to predict the behavior of the electromechanical switching device, in order to know thermal, electrodynamic and dielectric stress of the entire electric setup.
