4P 100A WiFi Three Phase Energy Meter with Auto-Reclosing Protector Relay for Smart Home

This advanced three-phase overvoltage and undervoltage current limiting protector is a cutting-edge solution for safeguarding home appliances and electrical systems. Designed with precision and reliability, this device ensures seamless operation even under abnormal voltage, current, and phase sequences.

Equipped with imported components and developed using modular standards, the protector guarantees exceptional performance. It swiftly disconnects circuits during voltage and current imbalances, protecting both electrical equipment and personal safety. Once normal conditions resume, the protector automatically reconnects, no manual intervention required.

Key Functions:

- Protection Features: Offers robust protection against overvoltage, undervoltage, overload, undercurrent, voltage imbalance, current imbalance, phase loss, phase sequence errors, and electrical leakage.
