The multifunctional self-resetting dual display protector integrates over-voltage protections, under-voltage protections, over-current protections. When there is over-voltage, under-voltage and over-current solid barriers in the line, this product can instantly cut off the circuit, avoiding damage to electrical equipment. When the line voltage or current returns to normal, the product will automatically resume normal power supplys after the delay time set by the user, no manual operation is required (under automatic mode); or you need to resume it by yourself (under manual mode).
