Lovato RFE Contactor Relay, 8 A, 5.5 kW

The RFE..electronic thermal overload relays for BF series contactors characterized by a wide current adjustment range and high reliability and accuracy of tripping.they are self powered by the main current and therefore do not require separate auxillary supply voltage.RFE electronic thermal overload relays are suitable for all types of motor starting thinks to the possibility to select several tripping classes.A single front push button is used to select the reset function,manual or automatic,and to activate or deactivate the STOP function
