FAQ

What is the main function of the RM35TF30 relay?

The RM35TF30 is a monitoring relay that protects 3-phase electrical systems. It checks for correct phase sequence, the loss of one or more phases, and ensures the voltage stays within a user-defined range (overvoltage and undervoltage protection).

How do I set the overvoltage and undervoltage trip points on this device?

The trip points are set using the potentiometers located on the top of the unit, under the transparent cover. You can adjust the thresholds for overvoltage and undervoltage as a percentage of the nominal supply voltage, according to your application’s requirements.

Is this relay suitable for both Delta and Wye (Star) connected systems?

Yes, the RM35TF30 can monitor 3-phase supplies without a neutral connection, making it suitable for both 3-wire Delta and 4-wire Wye (Star) systems, as long as the phase-to-phase voltage is within the 220-480V AC range.
