1. An electric unit, comprising a luminaire (1), which is provided for connecting to a mounting rail (50) having an elongated mounting rail profile (55), which together with two lateral walls (56) encloses a receiving chamber, in which at least one busbar (60) having longitudinally extending, contactable lines (70) is arranged, wherein the lines (70) of a busbar extend alternately in at least two planes that are aligned parallel to one another and spaced apart from one another (A1, B1),
wherein the electric unit comprises means for contacting the lines (70) of the busbar (60), said means comprising at least one rotatable contacting element (30, 40), on the outer circumference of which are arranged contacts (32, 42), which are pivoted outwardly when the contacting element (30, 40) is rotated and brought into abutment against the lines (70) to be contacted, wherein
said means for contacting the lines of the busbar comprises a first group of contacts (32) as well as a second group of contacts (42),
wherein the contacts of the first group are arranged with respect to an axis of rotation (I) of the contacting element (30) such that they are pivoted outwardly when the contacting element (30) is rotated such that they contact the lines (70) extending in a first plane (A1),
wherein the contacts of the second group are arranged with respect to an axis of rotation (I) of the contacting element (4040) such that they are pivoted outwardly when the contacting element (4040) is rotated such that they contact the lines extending in a second plane (B1), and
wherein the contacts of the first group (32) are arranged on a first contacting element (30) and the contacts of the second group (42) are arranged on a second contacting element (40), and the first contacting element (30) and the second contacting element (40) are arranged longitudinally spaced apart from one another on a supporting element (5) of the unit.
