An electrical engineering device is totally enclosed in plastics material , especially in an enclosure (1,2) in the form of a plastics housing, in which only the installation-, connection- or pluggable sockets (3) are placed in the front face of the enclosure (1,2), behind which, connection parts e.g. terminals or socket contacts are arranged i.e. flaps or slides (4) are arranged on the enclosure and are used to seal or cover the apertures. The part zone (6) containing the sockets and slides (4) or flaps of the front face of the enclosure is shaped and dimensioned so that the window of the front-face cover of the small installation distribution board is totally filled by this zone. |
