Overload Relay SS-30-N440 in Pakistan BR2649

 

Product Description:

 Two of three phase motor currents are monitored by current transformers.External Cts are  required for currents more than 60Amps.The internal solid state circuitry compares with the preset current time,the device trips,and changes internal SPDT relay contacts,Red LED remains illuminated indicating an overload trip has occurred.Until manual or remote electrical reset by interrupting supply,is initiated.
