Type 70.31 &#8211; Line voltage monitoring relay for three-phase networks. Multi-function model for monitoring three-phase (380 &#8230; 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 &#8211; selectable. 
Three-phase voltage control relay Type 70.31
Features include:
<ul>
<li>Positive safety logic (make output contact opens when the measured value is out of limits)</li>
<li>All functions and rating can be easily set using the front face selector and trimmer</li>
<li>“Blade + cross” – both flat blade and cross head screwdrivers can be used to select the function, adjust the trimmer and release the rail clip</li>
<li>Clear and immediate identification of the status through colored LEDs</li>
<li>1 changeover output contact &#8211; rated 6 A</li>
<li>Modular, 35 mm wide</li>
<li>35 mm rail (EN 60715) mounting</li>
<li>Cadmium-Free Contacts</li>
</ul>
