The invention relates to a device and a method for limiting the rail potential in a DC railway, a low-impedance link (4) being arranged between the rail (1) and the ground (2) below the structure. A switchgear (6) which is connected to a voltmeter (3) via a control line is connected to the link (4), the voltmeter (3) being arranged between the rail (1) and the ground (2) below the structure. According to the invention, the switchgear (6) comprises a thyristor (5), to the triggering input of which the voltmeter (3) is connected. An ammeter (7) which is connected to the triggering input of the thyristor (5) via a control unit (8) is connected to the link (4). Said control unit (8) keeps re-triggering the thyristor (5) until the value of the current has dropped below a threshold value.
