    (54) Electrode of vacuum circuit breaker


    (57) 57 An electrode for using in the vacuum circuit breaker, has at least one gap part, for generating the magnetic field in axial direction of its moving action. In an electrode of vacuum circuit breaker in accordance with the present invention, the electrode is constituted by a main electrode having at least one gap for generating the magnetic field in axial direction of its moving action, a sub-electrode having the same shape and disposed the back face of the main electrode. And the electric conductivity of the material of the sub-electrode is higher than that of the main electrode, for generating the magnetic field effectively in the axial direction.
