Abstract

According to an embodiment of the invention, a motor starter includes a connection module, which includes a second and third interface, wherein the second interface is electrically conductively connected to the third interface. The security evaluation unit can be mechanically coupled to the connection module so that an electrically conductive connection is produced between the first and second interfaces. The secure switch unit can be mechanically coupled to the connection module so that an electrically conductive connection between the third and fourth interfaces is produced, so that, in the coupled state of the security evaluation unit and the secure switch unit to the connection module; there is an electrically conductive connection between the first and fourth interfaces via the connection module, so that the control command can be transmitted from the security evaluation unit via the connection module to the secure switch unit.
