A current-carrying profile with an electrically insulating profile element (2a, 2b) is described which has grooves (4a, 4b) extending parallel to one another in a longitudinal extension direction (L) of the profile element (2a, 2b). The grooves (4a, 4b) are bounded by a pair of groove side walls (5) and have a groove bottom (6). The current-carrying profile has electrical conductors (3) which are received in the grooves (4a, 4b) of the profile element (4a, 4b) and extend parallel to one another in the longitudinal extension direction (L) of the profile element (4a, 4b). The profile element (4a, 4b) has on one end side projections (7). The projections (7) are formed from a groove side wall (5) or from a group of groove side walls (5) with an intermediate groove (4a, 4b) and for immersion in a recess (8) at an end face of an adjacent profile element (2a, 2b). educated.
