1. An electrical arrangement for protection in a direct current electric system, the electrical arrangement comprising:
an input connection with a positive input terminal and a negative input terminal;
an output connection with a positive output terminal and a negative output terminal;
a stepping converting component with at least one switching topology that has a first positive connector, a second positive connector and a ground connector, wherein a first switch is between the first positive connector and the second positive connector, and a second switch is between the second positive connector and the ground connector;
wherein the negative input terminal and the negative output terminal are connected via the ground connector;
wherein the at least one switching topology is connected to the positive input terminal by the first positive connector, to the positive output terminal by the second positive connector, and to the interconnected negative input and output terminals by the ground connector;
wherein the stepping converting component is configured to provide an operation mode for normal operation of the direct current electric system and to provide an overcurrent switching mode for overcurrent operation of the direct current electric system;
wherein a control signal for triggering a change from the operation mode to the overcurrent switching mode is to be provided to the electrical arrangement in response to a current within the electrical arrangement exceeding a predetermined threshold; and
wherein the first switch and the second switch are both not clocked to thereby prevent the first switch and the second switch from altering between different switching states during the operation mode.
