Abstract

An electric protective switching device is configured as a modular system and includes a switching device base module including first mechanical guide elements and an installation space with electric contacts. A control module including control electronics, first mechanical elements and electric counter-contact elements is installable into the installation space. A communication module including second mechanical elements is configured as an interface between the control electronics and an electronic bus system. The control module and the communication module are connectable mechanically and electrically to the switching device base module. The first mechanical guide elements of the switching device base module are configured to slidably receive the first mechanical elements of the control module and the second mechanical elements of the communication module in a plugging sequence wherein an electric contacting between the communication module and the control module is only established when, in the plugging sequence, the second mechanical elements of the communication module are connected to the first mechanical guide elements of the switching device base module before the first me…
