<p>The subject matter of the invention is an electrical apparatus (1) having a screw terminal for connecting electrical conductors, comprising a housing (3) with an upper face and a lower face (5, 7) and at least two screw shafts (9) which are arranged next to one another in the housing (3), wherein the screw shafts (9) each have a screw feed opening (12) on the upper face (5) and extend in the direction of the lower face (7). A transition region (11) connects the screw shafts (9) to one another. Projections (17) are arranged on the inner face of the screw shafts (9). The invention is characterized in that the projections (17) end at or beneath the level of the upper face (5) of the transition region (11), as viewed from the lower face (7), and also the projections (17) are arranged only outside the transition region (11), or at least one first projection (17) is provided outside the transition region (11) and a second projection is provided inside the transition region (11), wherein the radial extent of the second projection is less than that of the first projection (17).</p> |
