Abstract
A circuit breaker device is for coupling a DC voltage branch to a positive and a negative conductor on a DC voltage bus. In an embodiment, the circuit breaker device includes a series circuit including a safety fuse and a unidirectional switch module. The switch module has a parallel circuit includes a controllable semiconductor switch element that is conductive in a first current direction and a diode that is conductive in the opposite current direction.
