  • Air-break circuit interrupter having magnetically-assisted arc-dividing electrodes
    Patent number: 4041356
    Abstract: Air-break circuit interrupter having a plurality of stacked plates of insulating material straddled at the lower edge thereof by electrodes including diverging wing portions extending between the plates to permit the initial arc to be divided by the base portion of the electrodes into a number of elementary arcs extending between the plates to define a helical current path. Inserts of ferromagnetic material are sandwiched between the upstanding legs of the base portion of the electrodes interconnecting the wings thereof in order to enhance the migration of the arc roots along the base portion preventing their stagnation thereon.
