(54) Overvoltage protection device


(57) An overvoltage protection device (10), comprising a plug (11) which can be inserted in a power outlet and whose three terminals (12a, 12b, 12c), two (12a, 12b) for connection to the phases and one (12c) for connection to the ground, are associated with an electric circuit (16). The circuit is contained in a box-like body (15) which is rigidly coupled to a base (14) for supporting the terminals and comprises a first and a second varistor (17a, 17b) which are respectively connected between each terminal for connection to the phases and the ground connection terminal. The two phase connection terminals are further connected so as to have two parallel branches (18, 19), the first branch (18) being provided with a varistor (17c) and the second branch (19) being provided with a dissipative resistor (20) and a lamp (21) which are connected in series.
