Under/Over Voltage Relay 1-Phase 230VAC – SPDT Contact

A compact 1-module DIN rail-mounted voltage monitoring relay designed to protect single-phase 230VAC circuits from dangerous overvoltage and undervoltage conditions. The relay features adjustable thresholds (75–95% for undervoltage, 105–125% for overvoltage) with a response time range of 0.2–10 seconds and de-energises after the set delay period. Ideal for electrical installations, panel building, and industrial control applications where voltage stability is critical.
