20365-3071 ABSTRACT OF THE DISCLOSURE ELECTRICAL SWITCHGEAR HAVING AN INSERTABLE AND RETRACTABLE APPARATUS RACK A switchgear features insertable and retractable apparatus racks, which are to be connected by means of break- contact devices to current supply conductors (busbars) and to outgoing conductors. The busbars are configured to lie one behind the other in the moving direction during insertion and retraction. Both break-contact configurations are simultaneously actuated by means of a mutual driving arrangement consisting, for example, of a shaft, pinions and gear racks. The result is that when the break-contact configurations are closed, the apparatus rack is mechanically blocked in a reliable manner so that it cannot become displaced.
