[Scope of utility model registration request] It consists of a vacuum container, a pair of conductive rods arranged in correspondence with each other extending from the inside of the vacuum container to the outside, and a pair of electrodes that can be connected to and separated from each other and connected to the conductive rods in the vacuum container, and parallel to the generated arc. In vacuum circuits that employ parallel magnetic field electrodes that utilize the principle of diffusing and extinguishing arcs by applying a strong magnetic field, the electrodes are connected between the conductive bar current collectors with a two-line circuit, and the current collectors are In the section, the conductive rods constituting the two circuits are isolated by an insulator, and one circuit of the conductive rods constituting the two circuits is connected to the main electrode, and the other is connected to an electrode that generates a magnetic field parallel to the arc. Vacuum circuit breaker with special features.
