Type 70. 42, Line voltage monitoring relay for three-phase networks. Multi-function model, for monitoring three-phase networks (380 … 415 V, with neutral). Monitoring modes: undervoltage, overvoltage, window (overvoltage + undervoltage), phase rotation, phase loss, neutral loss (selectable), voltage asymmetry. Selectable Fault MemoryFeatures include: Detects phase failure error even in the presence of regenerated voltages, Positive safety logic (make output contact opens when the measured value is out of limits), All functions and values can be easily set using the selectors and front regulators, “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, 2 changeover contacts 8 A, Modular, 35 mm wide, 35 mm rail (EN 60715) mounting, Cadmium-free contacts
