General
The Three‑Phase Multifunctional Protector is an intelligent protection device integrating over‑voltage, under‑voltage, over‑current, leakage, power overload, and temperature protection. When any fault occurs, it instantly cuts off power to prevent equipment damage. All protection thresholds are user‑adjustable to match local conditions. The device automatically restores power after a delay when the line returns to normal. It also displays voltage, current, power, power factor, frequency, temperature, and energy values.
