<p>A primary electric circuit interrupting device, in particular for electric vehicles, provides that a fuse (3', 3") comprising a melting member (3 Γ, 31") and a varistor (32', 32") is integrated within each of two electric conductors (21, 22), by means of which each driving unit (1) is connected with each electric energy source (2). Each varistor (32', 32") in each fuse (3', 3") is arranged in electric contact and simultaneously also in a heat-conductive contact with each belonging melting member (3 Γ, 31"), and moreover, each varistor (32', 32") is electrically connected with a switch (4) intended for establishing or interrupting the electric interconnection between both varistors (32', 32") of said fuses (3', 3").</p> |
