| Datasheet | Download Datasheet |
The Finder 70.31.8.400.2022 is a 35 mm voltage monitoring relay with 1C SPDT output and rated 6 A at 250 V AC, driven by a 380 to 415 VAC input.
It watches all three phases for undervoltage, overvoltage or window, phase loss (even with regeneration) and phase rotation, with selectable fault memory, measuring true RMS voltage.
The undervoltage trip point covers 300 to 480 V (voltage detection range).
It trips after 0.5 to 60 s (adjustable) and re-energises 1 s after the fault clears.
It has DIN Rail mounting and box clamp terminals.
