Automatic Over/Under Voltage Delay Circuit Breaker

The Self-resetting Overvoltage Undervoltage Protector is an advanced electronic device designed to safeguard electrical equipment from damaging voltage anomalies. This fully automatic protector continuously monitors the supply voltage and disconnects the load when overvoltage or undervoltage conditions are detected, then automatically reconnects after the voltage returns to normal levels with a preset delay. This self-resetting function eliminates the need for manual intervention, significantly reducing system downtime and protecting sensitive appliances in residential, commercial, and industrial settings. Engineered for both single-phase (AC230V) and three-phase (AC380V) systems, the protector offers adjustable trip thresholds to suit diverse applications. A clear LED indicator provides instant visual fault status, enabling quick diagnostics. Optional temperature protection triggers at ≥80°C and recovers at ≤50°C, adding an extra layer of safety against overheating. The device consume…
