Features:1. LCD display with backlight , can display total active energy (kWh) , real time current (A) , voltage(V) , active power (W).2. LCD display kWh (4 digital+1 decimal) , Bi-directional total active energy measurement ,reverse active energy measure in the total active energy.3. Product self-design has function of lighting protection.4. Overvoltage protection, under voltage protection and over-current protection can select auto-Reclosing pattern or manual-Reclosing pattern.5. In case of over-voltage fault, under-voltage fault or over current fault in single phase line, the product can power off the line and can automatically restore connecting the line over a time delay after voltage of the lien is recovered to normal condition.6. In case of transient over voltage in line, the product can protect the equipment from false operation.7. In case that the line subjects to unstable voltage or sudden power-off and power-on due to
