Type 70.31 – Line voltage monitoring relay for three-phase networks. Multi-function model for monitoring three-phase (380 … 415)V undervoltage, overvoltage, window mode (overvoltage + undervoltage), phase rotation and phase loss (detects phase loss error even in the presence of regenerated voltages)
Voltage fault memory – selectable.
