Arrangement for cathodic protection from corrosion of metal bodies surrounded by an electrolytic medium, comprising a metal anode body which is to be introduced into the medium and has a lower (electric) quiescent potential in the medium than the bodies to be protected, where, by means of circuit comprising at least Schottky diode operating above a certain threshold voltage, one of the bodies to be protected and another one of the bodies to be protected have a difference in potential which is at least equal to the threshold voltage, but smaller than the quiescent-potential differences of the two bodies.
