The invention relates to a switching and protecting device for a high-voltage vehicle electrical system. The invention also relates to a vehicle, preferably a utility vehicle, having a switching and protecting device of this type. The switching and protecting device (1) comprises a contact pairing (2) having a double contact point, wherein two fixed contact pieces (2a) can be electrically connected and disconnected by means of a movable contact bridge (2b), and a controllable electromechanical drive (3), by means of which a control force on the contact bridge (2b) can be generated in order to selectively close and open the electrical connection. The switching and protecting device (1) also comprises a first control unit (4), which is formed as an application-specific integrated circuit, ASIC (4), or as a field-programmable gate array FPGA, or as a pure analog circuit by means of a comparator circuit. The first control unit (4) is designed to generate output signals for controlling the electromechanical drive (3), to determine, in accordance with an input signal, preferably a current- and/or voltage-based input signal, whether a first safety switch-off condition is satisfied, and, if the first safety switch-off condition is satisfied, to generate an output signal for opening the electrical connection.
