About this item

  • 【OUTPUT RELAY PROTECTION】In the case of reverse phase (reverse phase) , three phase voltage imbalance , lack of phase , short circuit , etc . during the of inductive loads such as motors , the 3 phase phase sequence relay can quickly determine and output relay
  • 【LONG TERM PROTECTION】The function of this phase sequence relay is not affected by the circuit or load current , current , unbalanced current and load characteristics , and realizes long term full performance and full climate to ensure the normal and stable of the motor
  • 【WORKING PRINCIPLE】Our phase sequence relay can detect the waveform and phase of the power supply through the integrated circuit to determine whether the power supply is abnormal
  • 【】This power supply monitor relay is made of materials and can maintain relatively stable performance for a long period of time
  • 【FOR 3 PHASE EQUIPMENT】The 3 phase sequence protector is suitable for various three phase motors and refrigeration compressors , pumps , fans , air compressors , elevators , injectionmachines and other three phase equipment


Characteristics of working for :

1 . If the connection of L1 , L2 and L3 phases are right , the green light of the relay illuminates and the relay closes . If they are wrong , the yellow light of the relay illuminates . Exchanging any two of them , the relay will accept the phase sequence and begin to work normally .
In this case that there occurs yellow light illuminated and relay unclosed after the protected equipment works normally , it should be a wrong connection of external circuit . The relay has a function ofagainst wrong connection .
2 . While any of these L1 , L2 and L3 phases is phase loss , the red light is lighted with the unlighted green light and the released relay . While the voltage come back to normal , it will recover immediately with lighted green light and closed relay .
3 . L1 , L2 and L3 connect with three phase AC . NO , COM are normally openpoint and NC , COM are normally closedpoint . Use to connect terminal directly .
