Abstract
A switchgear has insertable and retractable apparatus racks, which are to be connected by means of break-contact devices to supplying busbars and to outgoing conductors. The busbars are configured to lie one behind the other in a moving direction during insertion and retraction of the apparatus rack. Both break-contact configurations are simultaneously actuated by means of a mutual driving arrangement, for example, 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.
