This device continuously monitors the set threshold values and only generates a signal in the event of a genuine fault, minimising the risk of false alarms.

The system compares the measured current value with the threshold and time parameters set by the user. If the fault current persists for the specified duration, the device enters fault mode and transmits information via visual, digital and communication outputs.
