Abstract: An electrical circuit breaker system including an input terminal connecting an electrical current source and a plurality of output terminals for connecting electrical loads. Each output terminal includes an electrical switch and a current measuring unit. The circuit breaker system includes a current acquiring unit for acquiring current magnitudes measured at the output terminals and for determining a total current magnitude. A temperature acquiring unit acquires a temperature, and a computing unit is configured to determine a total current limit as a function of the acquired temperature. Further, a control unit is configured to select one of the plurality of output terminals based on a ranking of the output terminals and to interrupt the current supply at the selected output terminal by means of the corresponding electrical switch when the total current magnitude exceeds the determined total current limit.

Abstract: The disclosure relates to a circuit breaker with a monitoring device having an electronic switch and a mechanical changeover switch, where the mechanical changeover switch has a first terminal, a second terminal and a third terminal, where in a neutral position of the mechanical changeover switch the first terminal is connected to the third terminal and where in an operating position of the mechanical changeover switch the second terminal is connected to the third terminal, where the electronic switch is connected to the third terminal of the mechanical changeover switch as a series circuit, where when switching on the circuit breaker in a first switching state, initially the electronic switch is activated, where a measurement is taken at the first terminal using the monitoring device to determine whether essentially the same potential is present at the first terminal as at the third terminal and, it this is the case, the electronic switch is activated and the mechanical changeover switch is in an operating p

Abstract: The invention relates to a device circuit breaker having intelligent limit value determination. In a training phase, the device circuit breaker is adjusted to a specific device and its load behavior. In a subsequent monitoring phase—based on the values determined in the training phase—present values or values derived from those are compared and, if necessary, the current flow is interrupted.
