Abstract (en)
The electrical circuit breaker device includes at least one pair of superposed contact fingers (10,20) mounted respectively pivotably on two longitudinally offset transverse spindles (13,23). The electrodynamic forces of attraction A thus compensate for the forces of repulsion R. <IMAGE>
