The invention relates to a circuit arrangement (10) for suppressing an arc occurring during a switching process, wherein a current bypass path (104), which comprises a PTC resistor (105), is provided in parallel to a switch (101). The circuit arrangement (10) is characterized in that a fuse (106) is connected in series with the PTC resistor (105) in the current bypass path (104). The invention also relates to a photovoltaic power plant with a photovoltaic generator (1) which is connected to an inverter (5) via DC lines (2, 3). In this arrangement, such a circuit arrangement (10) is arranged in at least one of the DC lines (2, 3). |
