The utility model relates to a device for short circuit protection of an electrical system and an electrical system. The electrical system is provided with an energy storage device (10), a direct-current voltage intermediate circuit (20) and a direct-current voltage converter (30) connected between the energy storage device (10) and the direct-current voltage intermediate circuit (20), wherein the energy storage device on the direct-current voltage converter is switched on by means of the direct-current voltage converter and through a safety device (F). The device is provided with a switch mechanism (T2, T1 and 40); and the switch mechanism is used for switching on the voltage of the direct-current voltage intermediate circuit (20) by means of the safety device (F), so that responses can be made to detection of short circuits in the electrical system. The electrical system is provided with the device for the short circuit protection of the electrical system. |
