Digital electronic overcurrent trip device

摘要

The invention relates to a digital electronic overcurrent trip device for a switching apparatus, having a microprocessor for evaluating the measurement voltage and having a device for adjusting the tripping parameters, there being allocated to the microprocessor an electrically erasable, programmable read only memory (EEPROM) for storing the tripping parameters, and an interface for connection of a data input and erasing apparatus for access to the read only memory (Figure 1). <IMAGE>
