230V 40A Adjustable Voltage Protector with DIN Rail Mount

A DIN rail voltage protection device designed to monitor and protect compatible AC electrical circuits from overvoltage, undervoltage, and overcurrent conditions. The dual LED display shows voltage and current information for easier real-time monitoring, while the adjustable settings allow the cutoff ranges to be configured based on the connected system requirements. The auto-recovery function helps restore operation after voltage returns to the selected safe range.
