  • the circuit breakers are essentially only the emergency shutdown in the event of an extraordinary event, such as a short circuit at the output of the cabinet or the shutdown due to an overload that can not be handled by path switching.
  • the temperature of a conductor and / or the current flowing through the conductor is determined with the first sensor and transmitted to the controller. In this way, very good overloads or unbalanced loads can be detected in the system. If the current measured with the first sensor exceeds the first threshold value and / or the temperature measured with the first sensor exceeds the second threshold value, then the controller sends a signal to open to a first circuit breaker in the first path and a signal to close to a second path lying second circuit breaker. The output is then connected via the second path in which the second circuit breaker is located. In a very analogous way, the output can be connected in sequence via the first path or via another path to the input.
  • An overload in a path may not only be due to the tripping characteristic and the rated current of a circuit breaker located in this path, but may also be caused by a too loose fit in this path or loosening over time. Therefore, it is also particularly advantageous if the at least one output within the cabinet by

  • the path switching can therefore be performed close to the limit of the overload in the first path.

It is particularly advantageous in this context if the shortest distance between the at least one sensor and the first circuit breaker is a maximum of 100 mm. This also favors a path switch close to the overload. In particular, the circuit breaker threatened by overload is directly relieved by the path switchover. In the same way, it is advantageous if, alternatively or additionally, the shortest distance between the at least one sensor and a screw in the first path is a maximum of 100 mm. In this way it can be determined if a

  • this can be accomplished by the fact that a rated current of a first circuit breaker located in the first path is the same as a rated current of a second circuit breaker located in the second path. In this way, the device connected to the output of the cabinet is not or hardly affected by the switching of the path.
