Electrical circuit breaker system with temperature-dependent total current monitoring

An electrical circuit breaker system comprising:

• an input terminal for connecting an electrical current source;
• a plurality of output terminals each for connecting electrical loads, each output terminal having an electrical switch for interrupting a current supply, and a current measuring unit for measuring an individual current magnitude;
• a current acquiring unit for acquiring the individual current magnitudes measured at the plurality of output terminals and for determining a total current magnitude corresponding to a sum of the individual current magnitudes;
• a temperature acquiring unit for acquiring a temperature;
• a computing unit configured to determine a total current limit as a function of the acquired temperature;
• and
• a control unit 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.
