This multifunctional adjustable voltage current protector integrates over-voltage, under-voltage, and over-current protection. It instantly cuts off the circuit when abnormal voltage or current occurs to avoid damage to electrical equipment. When the line returns to normal, it auto-recovers after user-set delay (auto mode) or needs manual reset (manual mode).
