Blog Article

The Schneider RM17TG00 is a phase control relay designed to monitor three-phase systems for faults such as phase loss, phase sequence reversal, and voltage imbalance. It helps protect motors, generators, and other three-phase equipment from damage due to power supply issues.






Key Features of Schneider RM17TG00


✔ Phase Loss Detection – Detects if one or more phases are missing.
✔ Phase Sequence Monitoring – Ensures correct rotation (L1-L2-L3).
✔ Voltage Imbalance Protection – Prevents motor overheating due to unequal phase voltages.
✔ Adjustable Thresholds – Configurable voltage limits for different applications.
✔ LED Indicators – Shows power status and fault conditions.
✔ Compact DIN Rail Mounting – Easy installation in control panels.
✔ Wide Voltage Range – Supports 208-480V AC (50/60Hz).

Applications




  • Motor Protection (Pumps, fans, compressors)




  • Generator & UPS Monitoring




  • HVAC & Industrial Automation




  • Machine Safety Systems







Adjustment & Settings




  • Phase Sequence – Can be set for L1-L2-L3 or L3-L2-L1.




  • Voltage Imbalance Threshold – Typically 10-30% (adjustable).




  • Time Delay – Prevents nuisance tripping (0.1s to 10s).







Alternatives (If RM17TG00 is Unavailable)




  • Siemens 3UG4613-1AR30 (Similar phase monitoring relay)




  • ABB CM-MPS.41S (Compact phase control relay)




  • Eaton MNR-MDP (Digital phase monitor)







Troubleshooting Tips


???? Red LED ON – Indicates a fault (check phase loss, sequence, or imbalance).
???? Green LED OFF – No power supply (check wiring).
⚡ False Tripping – Adjust voltage thresholds or delay settings.https://store.unigulfsupply.com/product/schneider-rm17tg00-phase-control-relay/
