In 3-phase networks, it detects undervoltage or phase failure early on and intervenes before damage occurs.

⚡ Your benefits:
✔️ Prevents malfunctions in motors and control systems
✔️ Ensures safe shutdown in the event of a voltage drop
✔️ Defined restart after voltage recovery

🔍 How it works:
🟢 Voltage OK → Relay energizes
🔴 Undervoltage (>0.5 s) → Relay de-energizes, fault indicator active

💡 Highlights:

▪️ Compact (1 TE)
▪️ 3-phase monitoring + phase failure
▪️ Optional: Neutral conductor, rotating field indicator, test button
▪️ Power consumption < 1 W

📍 Applications: Control cabinet, emergency lighting, motor controls

💥 Fun Fact: The test button (Part No. 103031) allows you to simulate a specific fault.

👉 Greater grid safety – simple & effective.
