This is a kind of quality intelligent leakage-protecting switch, that integrates an overvoltage protector, undervoltage protector, and overcurrent protector leakage protector. 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: Intelligent Interference Resistance: The use of intelligent chips, anti-interference to improve, solve the problems of frequency instability and screen waves, and others. Reliable Quality: Built-in 63A latching relay, high current shock does not burn. Multifunctional Design: It integrates an overvoltage protector, undervoltage protector, and overcurrent protector leakage protector.  Digital Display: It can display real-time electricity, voltage, current, and leakage value on the digital screen simultaneously, you can see the data clearly at a glance. Setting Function: Equipped with protections values setting function, you can set the protecting values of over current, low current, and leakage values and delay time according to your demands. 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 Wiring: Large wiring port design, makes the wiring process quicker and easier.  Easy Installation: Compact size suitable for installation in the distribution box, or mounted on the wall. Din rail type snap installation, no screws required, buckle fixation. Wide Applications: Suitable for a variety of occasions, such as rental houses, shopping malls, schools, factories, etc. Recommended for use with high-power products which are prone to leakage behavior, such as electric heaters, ovens, water heaters, refrigerators, air conditioners, etc. Two Types Available: You can choose the common version and the Tuya Wifi version according to your demands. Tuya Wifi version has the mobilephone APP control function. Tuya Wifi Version: Mobilephone Tuya APP controls the overvoltage, under-voltage, and current can be controlled through the APP and the data can be seen on the APP.
