This is a kind of quality intelligent power meter, that overvoltage, undervoltage, overcurrent, and leakage protections functions. When over-voltage, under-voltage, over-current, or leakage occurs in the line, this product can immediately cut off the power supplys to prevents electrical equipment from burning. The over-voltage, under-voltage, over-current and leakage protections values of this product can be set by yourself and can be adjusted according to the actual local situation. Features: Digital LCD Display: LCD digital display, it can display real-time electricity, voltage, current and leakage value simultaneously on the digital screen, you can see the data clearly at a glance. More accurate and easier to read. Mobilephone APP Control: Support Mobilephone Tuya APP remote real-time monitoring the overvoltage, under-voltage, and current can be controlled through the APP and the data can be seen on the APP online. Setting Function: Equipped with protections values setting function, you can set the protecting values of over voltage, under voltage, over current, leakage current according to your requirements. Support set the reconnect time, over current and leakage protect times. Support set between three timing modes of timing mode, countdown mode and cycle timing. Multiple Protections Design: It integrates overvoltage, undervoltage, overcurrent, and leakage protections. Automatic Reclosing: Intelligently identify the leakage and when it occurs overvoltage and under voltage, the protector will automatically cutoff the power supplys, if the fault has been eliminated, it will automatically reclose and turn on the power. Easy Installation: Compact size suitable for installation in the distribution box, or mounted on the wall. Din rail type snap installation, no screws required. Wide Applications: Application scenarios, suitable for household appliances management, remote management, housing rental use, industrial control equipment use, intelligent upgrade of power distribution equipment, etc. Specifications: Name: Automatic Reclosing Protector Material: plastics Rated voltage: AC230V Rated current: 1-63A Over-voltage protections: AC230-280V Over-current protections: AC150-190V Leakage protecting value: 1-99mA Item size: 85 * 36 * 66mm / 3.35 * 1.42 * 2.60in Package size: 89 * 72 * 41mm / 3.50 * 2.83 * 1.61in Package weight: 160g / 5.64ounce Packing List: 1 * Automatic Reclosing Protector
