A metallic three-phase substation has three circuit breaker per two feeders, and includes two busbars (B01, B02) to which a plurality of single-phase cells (14R, 16R, 18R, 14S, 16S, 18S, 14T, 16T, 18T) with separate phases are connected. The cells are provided with circuit breakers (20R, 22R, 24R, 20S, 22S, 24S, 20T, 22T, 24T) which are aligned longitudinally according to a direction parallel to the busbars (B01, B02) and which are housed in vertical enclosures, located at regular intervals along the busbars. The lower and upper transverse connections of the circuit breakers extend respectively in two planes parallel to the bushbars (B01, B02).
