The invention relates to an apparatus insert for pushing into telecommunications mounting racks having at least one populated printed circuit board, which is pushed into internally located grooves, and having at least one heat sink on the front. It is intended to be constructed such that the operation of the assembly accommodated on the printed circuit board is possible without any deterioration in the cooling, even when the printed circuit board is not pushed into the apparatus insert, and reliably constant good cooling is intended to be ensured during operation, over a long time. To this end, the heat sink is mounted on the printed circuit board in close thermal contact with thermally stressed components, which are arranged on this printed circuit board, and projects through a cut-out in the front panel of the apparatus insert. Telecommunications apparatuses.
