摘要： A monitoring device having a switching mechanism to open or close electric circuits in case of overload which operates as a function of a current-detecting device includes a processor and setpoint memories for comparing and evaluating actual values. A device for detecting additional load operational errors, statistical operating data, and maintenance instructions from at least the load current over the lifetime of the device and providing a run display to display this data are consecutively integrated into the monitoring device. Furthermore, input keys are provided for setting desired parameters, which can be displayed in the run display.
