The invention relates to an electrical module (50) for connecting to a mounting rail, comprising a contacting element (10) which is rotatably mounted about an axis of rotation (I) such that it can move between an open position in which an insertion and removal of the contacting element (10) from the mounting rail profile (60) is enabled, and a contacting position in which connection contacts contact lines of a bus bar, wherein the contacting element (10) has a main body (15) rotatably accommodated in a carrier element (30) of the electrical module (50) and a contact holder body (20) holding the connection contacts, which is arranged on the main body (15) and rotates with same, and wherein the contact holder body (20) is mounted such that it can be adjusted along the axis of rotation (I) relative to the main body (15) between a blocking position in which a rotation of the contacting element (10) is blocked, and a release position in which a rotation of the contacting element (10) is enabled.
