摘要： The invention relates to an interrupter device (10) for interrupting a direct current between a direct-current source (2) and an electric device (6), in particular between a photovoltaic generator and an inverter. The interrupter device (10) comprises a mechanical switch (16) which has a first fixed contact (18), a second fixed contact (20), and a contact bridge (22) that can be moved between a first position (32) and a second position (34). In the first position (32), the first fixed contact (18) and the second fixed contact (20) are electrically contacted by means of the contact bridge (22), and in the second position (34), the contact bridge (22) is arranged at a distance from the first fixed contact (18) and the second fixed contact (20). The contact bridge (22) and the first fixed contact (18) are electrically contacted by a semiconductor switch (40) which blocks a current when the contact bridge (22) is in the first position (32). A control input (44) of the semiconductor switch (40) is connected to the mechanical switch (16) such that an arcing voltage (64) generated as a result of an arc (60) across the switch (16) connects the semiconductor switch (40) so as to conduct a current when the contact bridge (22) is moved into the second position (34).

摘要： The invention relates to a circuit breaker for interrupting an electrical circuit when current limit values are exceeded, said circuit-breaker having a current sensor for determining the electrical current flowing through the circuit-breaker and being connected to a control device of the circuit-breaker. When current limit values are exceeded, the electrical circuit is interrupted. Defined are: a nominal current of the circuit-breaker; a first current limit value, which is a multiple of the nominal current and which, when exceeded, results in an immediate interruption; a second current limit value, which is less than or equal to the nominal current and which, when exceeded, results in a time-delayed interruption, such that the second interruption time reduces as the current increases. The circuit-breaker has only one control element for setting a current limit value, said element defining the second current limit value for the time-delayed interruption of the electrical circuit. The other parameters are either set in a fixed manner and/or are related to the settable or set second current limit value Ir.
