Electronic voltage monitoring relays for 
single and three-phase applications
Multifunctional types, providing the flexibility 
of monitoring Undervoltage, Overvoltage, 
Window Mode, Phase rotation, Phase loss, 
Asymmetry and Neutral loss
Positive safety logic - Make output contact 
opens if the relay detects an error
All functions and values can be easily adjusted
by the selector and trimmer on front face
“Blade + cross” – both flat blade and cross 
head screw drivers can be used to adjust the 
regulators and the function selector
Colored LEDs for clear & immediate visual 
indication
1 CO relay output, 6 or 10 A
Modular housing, 17.5 or 35 mm wide
35 mm rail (EN 60715) mount
Cd-free contact material
