Abstract
An arcing fault recognition unit is for an electric low-voltage circuit. In an embodiment, the arcing fault recognition unit includes at least one current sensor for periodically ascertaining electric current values in the electric circuit, the current sensor being connected to an analysis unit which is designed in such a way that an arcing fault recognition signal is output when a variation in the rate of current rise exceeds a first threshold value or drops below a second threshold value.
