This is a kind of quality protecting switch, that integrates an overvoltage protector, undervoltage protector, and overcurrent protector. LCD display design, it can real time displays two data 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. 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. Features: Multifunctional Design: It integrates the functions of an overvoltage protector, undervoltage protector, and overcurrent protector leakage protector. Built-in intelligent chips, wear resistance, interference resistance, high strength and with fine durability. Digital Display: Dual displays design, it can real time displays two data on the digital screens simultaneously, large font design for you to see the data clearly at a glance. Current Adjustable: Built-in adjustable chip, can be customized to adjust the current, you can adjust the current and over-under-voltage protecting value to protect the daily use of the process of different situations. 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. 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. Specifications: Name: Automatic Reclosing Protector Material: plastics Rated current: 40A,63A (optional) Rated voltage: 230VAC Over-voltage protecting value: 230-280V Item size: 85 * 36.5 * 65.5mm / 3.35 * 1.44 * 2.58in Item weight: 140g / 4.94ounce Package size: 45 * 95 * 75mm / 1.77 * 3.74 * 2.95in Package weight: 170g / 6.00ounce Packing List: 1 * Protector
