Switching device, particular circuit breaker, for selectively switching off electrical conductor, comprises multiple current branches, where multiple switching elements are opened by triggering one of multiple overload releasing elements

摘要

The switching device (1) comprises multiple current branches that are electrically connected in parallel. A short circuit triggering system is operatively connected with multiple switching elements. A different current limit is provided for each current branch. The switching elements are opened by triggering one of multiple overload releasing elements.
