RFE... electronic relays are characterized by a wide current range and high precision in tripping time.RFE... are self powered by the power circuit current, so they do not require auxiliary power supply. RFE... are suitable for all types of motor starting because different tripping classes (5, 10, 20 or 30) can be selected.
