Low-voltage circuit breaker device

A low-voltage circuit breaker device, comprising:

• at least one outer conductor path from an outer conductor supply terminal of the low-voltage circuit breaker device to an outer conductor load terminal of the low-voltage circuit breaker device;
• a neutral conductor path from a neutral conductor terminal of the low-voltage circuit breaker device to a neutral conductor load terminal of the low-voltage circuit breaker device;
• a mechanical by-pass switch arranged in the outer conductor path;
• a semiconductor circuit arrangement of the low-voltage circuit breaker device connected in parallel to the bypass switch;
• an electronic control unit;
• and
• a current measurement arrangement arranged in the outer conductor path and connected to the electronic control unit,
• wherein the electronic control unit is configured to actuate the mechanical by-pass switch and the semiconductor circuit arrangement upon detection of a predefined overload current, comprising a short-circuit current, by the current measurement arrangement,
• wherein the semiconductor circuit arrangement comprises at least one first semiconductor component and at least one second semiconductor component, and
• wherein the at least one first semiconductor component is arranged on a first side of a component carrier, and the at least one second semiconductor component is arranged on a second side of the component carrier facing away from the first side.
