A power supply in which a feed voltage (U<SUB>s</SUB>) is guided through at least one longitudinal branch to at least one output, the at least one branch having a disconnect fuse formed as a controlled semiconductor switch (SW 1 ) and a monitoring unit (UWE) being set up to supply a disconnect signal (s 1 ) to the semiconductor switch when there are changes in voltage or current beyond pre-definable tolerances, in which at least one auxiliary semiconductor switch (H 1 A), likewise triggered by the monitoring unit (UWE), is connected in parallel to the semiconductor switch (SW 1 ) and in the event of an overload absorbs a substantial portion of the overload current in the branch.
