3 PHASE 4 WIRE WI-FI ENABLED TUYA SMARTLIFE SMART ENERGY METER + PROTECTOR WITH AUTO RECLOSE

TUYA WiFi SMART THREE-PHASE AUTOMATIC RECLOSING CIRCUIT BREAKER WITH POWER METER (3P4W) IN SRI LANKA

In Stock

This smart protection and energy monitoring device is designed to provide comprehensive electrical safety and precise power management for single-phase systems. It integrates over-voltage, under-voltage, over-current, and under-current protection with adjustable delay control, ensuring stable operation and effective protection against abnormal electrical conditions. The built-in timer switch and bidirectional energy monitoring enable accurate tracking of power consumption and generation. Advanced protections such as voltage imbalance, current imbalance, phase loss, phase sequence, and high-temperature protection can be configured through the mobile app for enhanced system control. Residual current leakage protection, used with an external or built-in current transformer, further improves electrical safety. All protection parameters feature configurable thresholds with independent on/off control, allowing the device to be precisely tailored to residential, commercial, or industrial distribution applications.
