Abstract
A circuit breaker having two terminals, between which a current path is formed, to which a unit is assigned for the direction-dependent determination of an electric current carried via the current path. The current path has a first branch with two semiconductor switches electrically connected in series and opposite to each other, each comprising a control input and operated via a control unit corresponding to a time-current tripping characteristic. Via the time-current tripping characteristic, at least partially differing durations are given for different current strengths, from which the current path is interrupted, and wherein at least some of the durations differ for different current directions.

A circuit breaker comprising:
- two terminals, between which a current path is formed;
- a unit assigned to the current path for a direction-dependent determination of an electric current carried via the current path;
- and
- a first branch comprising two semiconductor switches electrically connected in series and opposite to each other, the two semiconductor switches comprising a control input and being operated via a control unit corresponding to a time-current tripping characteristic via which at least partially differing durations are given for different current strengths, from which the current path is interrupted,
- wherein at least some of the durations differ for different current directions.
