smART SP

Digital overcurrent protection specially designed to protect transformation centers that do not have auxiliary supply batteries, for the purpose of completing the protection of fuses or totally replacing them.

Powered by mains transformers, it is capable of tripping the switch, providing energy to the respective tripping element.

It provides information on an ongoing basis regarding:
 • the measurement of the current of the circuit being monitored (effective value),
 • the status of the relay protection units,
 • the accumulated value of KI²,
 • the date and time,
 • the status of the digital inputs and outputs,
 • it can store the information of the last sixteen events that occurred, storing the date, time, cause of the fault and values of the current inputs (only in models with the Clock and Event Log options).
