Multi-function phase control relays RM17TG20 for 3-phase supplies monitor the correct sequencing of phases L1, L2, and L3 and the total loss of one or more of these phases.
  • Monitor their own power supply measured as a true rms value.
  • Accept different nominal 3-phase voltage values within voltage range 183...484V;
  • Are designed for clip-on mounting on a 35mm DIN rail;
2 change-over contacts.
The control status is indicated by LED light.

Applications of relay RM17TG20

  • Control for connection of moving equipment (site equipment, agricultural equipment, refrigerated trucks).
  • Control against reverse motor operation (lifting, handling, elevators, escalators, etc.).
  • Control of sensitive 3-phase supplies.
  • Lighting and heating circuits control.
  • Emergency power supply switching in abnormal conditions.
