The Finder 70.31.8.400.2022 is a Line Monitoring Relay rated at 380 to 415VAC. The Relay is from the Finder 70 series and is for 35mm DIN rail mounting. This Electronic Voltage Monitoring Relay has screw terminals, and is ideal for three-phase applications. The multifunctional relay, provides the flexibility of monitoring Undervoltage, Overvoltage, Window Mode, Phase rotation, Phase loss, Asymmetry and Neutral loss.
Both flat blade and cross head screw drivers can be used to adjust the function selector, the timing trimmer, and to disengage the 35mm rail mounting clip.
