In a vacuum circuit interrupter of the type having two or more identical interrupting units mounted within an evacuated housing, a plasma screen is formed for the arc created by interruption of the current between a stationary and a movable contact for each of the interrupting units by a helicoidal winding of conductive material electrically connected with the electric current circuit of the associated interrupting unit for the generation of a magnetic field which encloses the plasma generated therein. |
