Type 70.31 - Line monitoring relay

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.
Three-phase voltage control relay Type 70.31

Features include:

• Positive safety logic (make output contact opens when the measured value is out of limits)
• All functions and rating can be easily set using the front face selector and trimmer
• “Blade + cross” – both flat blade and cross head screwdrivers can be used to select the function, adjust the trimmer and release the rail clip
• Clear and immediate identification of the status through colored LEDs
• 1 changeover output contact – rated 6 A
• Modular, 35 mm wide
• 35 mm rail (EN 60715) mounting
