The multifunctional self-resetting dual display protector integrates over-voltage, under-voltage, and over-current protections. When over-voltage, under-voltage, or over-current occurs in the line, it instantly cuts off the circuit to avoid damage to electrical equipment. When voltage or current returns to normal, it automatically resumes power supply after the user-set delay time (automatic mode) or requires manual reset (manual mode).
