ABSTRACT OF THE DISCLOSURE: A current limiter according to the invention has two resistors, the first one consisting of a thin layer of a material which may become superconducting and the second one is a resistance layer applied on first resistor, the latter resistor layer being dimensioned such that its resistance becomes considerably lower than the resistance of the superconducting layer when it is not superconducting, however with a resistance of such a magnitude that, in the current circuit in question, it limits the current to a permissible value. For mechanical support of the resistors, an insulator is included in the current limiter, and the superconducing material is applied on insulator. The resistors and the insulator are arranged immersed into a cryotank.
