The second switching point (3) is designed to disconnect a short-circuit current which is a multiple of the maximum continuous current.

Unlike a circuit breaker a contactor is not intended to interrupt a short circuit current.

The switching device (1) has a first switching point (2) for normal switching of at least one current path (L1-L3), and has a second switching path (3) for disconnection of a short-circuit current.
