Abstract
A protective device comprises an input, an output, a first power switch, a second power switch and a drive unit. The first and second power switches are electrically connected in parallel with one another between the input and the output. The first power switch is configured to conduct a first forward current in a conducting state and to limit said first forward current in a current-limiting state. The second power switch is configured to conduct a second forward current in a conducting state and to interrupt said second forward current in an interrupting state. The second power switch comprises a lower on resistance than the first power switch. The switch arrangement is configured, for limiting the current flowing between the input and the output, to interrupt the second forward current with the second power switch and to limit the first forward current with the first power switch.
