Using the motor itself as a sensor and without requiring any external detectors, they monitor the cos φ of the motor and stop it before a breakdown occurs caused by dry running, cavitation or closed valve.

WITHOUT LEVEL SENSORS
- Without requiring level sensors to detected dry running.
- For three phase motors from 1 to 630 A and over. Cable feed through.
- Precise motor heating and cooling memory, reproduces its thermal image.
- Visual indication of tripping cause.
- Adjustable reset time for cos φ.
Protection Functions
