Finder offers a new range of Electronic voltage monitoring relays for single and three-phase application – in 17.5 or 35 mm housings.
Types 70.11, 70.31 and 70.41 cover the following functions and points of specification:
These relays join the type 70.61 for three-phase loss and rotation (replacing the type 72.31 as reported in the Finder News January 1 2012).
