Adjustable Over/Under Voltage Protector, AC220V 40A 2P DIN Rail Surge Protector Recovery

General Description: The overvoltage and overcurrent protector is an essential device for protecting your electrical equipment. It is designed to immediately cut off the power supply in the event of overvoltage, undervoltage, or overcurrent, thus protecting your devices from damage. This device automatically resets when the voltage returns to normal, providing a reliable solution for circuit protection in residential installations. Technical Specifications Rated Voltage: 220 VAC Input Voltage: AC 140-300 V Rated Insulation Voltage: 450 V Rated Operating Current: 40 A Output Contact: 1 NO Protection Level: IP20 Rated Frequency: 50/60 Hz Self-Power Consumption: ≤ 2 W Action Delay: 0.1 s - 30 s (1 s default) Power-On Delay: 1 s to 500 s (10 s default) Adjustable Overvoltage Range: AC 230-300 V (270 V standard) Adjustable Undervoltage Range: AC 140-210 V (170 V standard) Installation The voltage protector is designed for easy installation on a standard 35 mm DIN rail. No screws are required for installation, making it quick and convenient to fit. Application: This device is primarily used to protect distribution lines in residential junction boxes and for protecting single-phase electrical equipment. It is ideal for users with loads operating at a single-phase AC voltage of 220 V, 50/60 Hz, with an operating current of 40 A or less.
