Beschreibung
Zusammenfassung:	A circuit breaker device protects an electric low-voltage current circuit. A level of a voltage of a low-voltage current circuit is ascertained such that ascertained voltage values are provided. A differential voltage is ascertained from the ascertained voltage values and an expected value of the voltage such that differential voltage values are provided incrementally. Each differential voltage value is compared with a first threshold, and if at least two successive differential voltage values exceed the threshold, an interruption of the low-voltage current circuit is initiated by semiconductor-based switching elements, which are set to a high-ohmic state, in order to protect the low-voltage current circuit from a short-circuit.
