Abstract: The selective fault-current differential circuit breaker includes a toroidal totaliser current transformer (23) and a trip (36) whose energising coil is connected to the secondary winding (25) of the totaliser current transformer (23) across a circuit for tripping (33) which is independent of the voltage of the network. This circuit comprises a rectifier circuit (26) which provides at least one charging capacitor (34, 35) with the energy required to actuate the trip (36), and furthermore an electronic valve (38) controlled as a function of the charging voltage of the charging capacitor (34, 35) with a view to releasing this energy to the energising coil of the trip (36). In order to simplify the construction, there is provision for the usually expensive secondary winding (25) of the totaliser current transformer (23), to comprise only a small number of turns and to be wired to the primary winding (28) of a transformer (27) whose secondary winding (29) is connected to the rectifier circuit (26). <IMAGE>
