Abstract (en)
[origin: EP1376634A1] A semi-annular conducting shield (11) is electrically connected around the periphery of a movable arcing contact (4) so as to withstand the electric field arising from the recovery voltage imposed by the power system after breaking. The physical continuity on the stationary and movable arcing contacts (3,4), is achieved by the rings arranged on the contact surface of the movable and stationary contacts, respectively.
