Elektronische Überlastrelais Thermische Überlastrelais

Electronic Overload relay,Thermal Overload Relay Overload and Phase Loss Protection Independently adjustable starting and Trip Delay Visual Current Setting Aid&Trip Indication(LED) Flexible Power Supply(90 to 260VAC or 320 to 480VAC) Fail Safe Protection(N type) Description Two of three motor currents are monitored by current transformer.External Cts are required for currents more than 60Amps. The internal solid state circuitry compares with The present current level.When load currents exceeds the preset trip level,red LED illuminates,and after the preset time ,the device trips,and changes internal SPDT relay Contacts,RED LED remains illuminated indicating an overland trip has occurred.Until manual or remote electrical reset by interrupting supply,is initiated. If load current falls off below setpoint before the preset delay,device resets trip timer.With The visual aid of LED,flashing at 100% of preset load,actual load currents can be determined without the aid of Ammeter.TEST button providers the means of testing servive-worthiness and integrity of ready mode with either supply lost or own failure. Starting delay time range0.2-30 seconds. Trip delay time range0.2-10 seconds.May be used as electronic shearpin by setting trip time to minimum.
