Excessively high (or low) voltage can damage equipment and electronics. An overvoltage monitoring relay monitors the power grid and intervenes in a timely manner.

✔️ Prevents damage caused by voltage fluctuations

✔️ Detects overvoltage, undervoltage, and phase failure early

✔️ Ensures controlled shutdown or release when “Mains OK”

💡 Highlights 

▪️ Suitable for AC & DC

▪️ Adjustable thresholds

▪️ LED fault indicator

▪️ Power consumption < 1 W

📍 Applications: Control cabinets, industrial & building systems

❗ Important: Not a surge arrester – it measures and controls, but does not protect against lightning surges.

👉 More control. More safety. Fewer outages.
