This is a kind of quality protecting switch, that integrates an overvoltage protector, undervoltage protector, and overcurrent protector. LCD display design, it can displays real time voltage and current on the digital screens simultaneously. When over-voltage, under-voltage, over-current occurs in the line, this product can immediately cut off the power supplys to prevents electrical equipment from burning. The over-voltage, under-voltage and over-current protections values of this product can be set by yourself and can be adjusted according to the actual local situation. Features: Premium Material: The housing is made of flameresistant material, built-in intelligent chips, wear resistance, interference resistance, high strength and with fine durability. Multifunctional Design: It integrates an overvoltage protector, undervoltage protector, and overcurrent protector leakage protector. Digital LCD Display: LCD display design, it can displays real time voltage and current on the digital screens simultaneously, you can see the data clearly at a glance. Automatic Reclosing Protecting Function: When it occurs overvoltage and over current, the protector will automatically cutoff the power supplys to protects home apparatus, if the fault has been eliminated, it will automatically reclose and turn on the power. Multi-protections: With overvoltage, undervoltage, current limit, phase-break, zerolost, phase sequence, voltage unbalance protections. Protections Values Setting Function: You can set the protecting values of over current, over voltage and under voltage; the resume figure of over current, over voltage and under voltage; and set the recovery delay and acting delay times of over current, over voltage and under voltage according to your demands. 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. 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. Specifications: Name: Automatic Reclosing Protector Material: plastics Type: 63A380V, 63A230V,100A380V,100A220V (optional) Input voltage: 220 V; 50/60Hz Over-voltage protecting value: 230-300V, default 270V Under-voltage protecting value: 140-210V, default 170V Leakage protecting value: 10-99mA, default 30mA Power on delay: 1-500S, default 5S Over-voltage resume figure: 225-95V, default 265V Under-voltage resume figure: 145-215V, default 175V Continues protecting times: 0-20 times, default off Time delay value: 0.1-30s, default 0.5s Working temperature: -5 to 40 Storage temperature: -25 to 55 Electrical mechanical lifespan: 100,000 times Item size: 63A: 91 * 91 * 50mm / 3.58 * 3.58 * 1.97in 100A: 101 * 91 * 52mm / 3.98 * 3.58 * 2.05in Package size: 63A: 100 * 100 * 80mm / 3.94 * 3.94 * 3.15in 100A: 110 * 110 * 80mm / 4.33 * 4.33 * 3.15in Package weight: 63A: 400g / 0.88lb 100A: 500g / 1.10lb Packing List: 1 * Protector
