Claims (1)

[Claims for Utility Model Registration] 1. A movable electrode provided with a contact at one end and rotatably supported, a fixed electrode provided with a contact capable of contacting the contact of the movable electrode and opposed to the movable electrode, and the movable A current limiting device comprising a U-shaped core that generates an electromagnetic force that separates an electrode from the fixed electrode, and a tension spring that maintains contact pressure between the movable electrode and the fixed electrode, wherein the movable electrode is made of a ferromagnetic material. A current limiting device characterized by being constructed from a composite material with a good conductor. 2. The current limiting device according to claim 1, wherein the direction of the magnetic property of the ferromagnetic material through which magnetic flux easily passes is perpendicular to the direction of the current flowing through the movable electrode. 3. The current limiting device according to claim 2, wherein the ferromagnetic material is formed into a fiber shape. 4. The current limiting device according to claim 1, wherein the ferromagnetic material and the good conductive material formed in thin plate shapes are alternately laminated.
