Over Under Voltage Protector Adjustable Self Resetting Intelligent Voltage Protective Device AC220V 40A

Feature:1. FULL PROTECTION: The shell is made of PC flame retardant material, with overvoltage protection, undervoltage protection and voltage display, making it safer and more reliable to use.2. INTELLIGENT ADJUSTMENT: To provide safe protection for electrical appliances, manual adjustment of overvoltage, undervoltage, overcurrent protection value.3. THREE DISPLAY: The voltage protector's screen displays voltage, current, and kWh for more intuitive and convenient readings.4. MULTIPLE FUNCTIONS: The current protector has the functions of reset mode selection, fault query and factory recovery.5. PROTECTIVE DEVICE: The protector can prevent the frequent on/off of unstable voltage from causing additional damage to electrical appliances, and achieve secondary protection, and automatically restore power supply after 1 to 600S of voltage stabilization.Specification:Item Type: Over Under Voltage ProtectorMaterial: PCRated Power Supply Voltage: AC220VOperating Voltage Range: AC80V-400V (single item)Rated Frequency: 50/60HzOvervoltage (> U) Setting Range: 230-300VUndervoltage (< U) Setting Range: 210-140VkWh Protection Value: 1-9999> U And < U Trip Delay: 0.5SReset or Startup Delay: 1-600SVoltage Measurement Accuracy: 2% (not more than 2% of the total range)Rated Insulation Voltage: 400VOutput Contact: 1NOElectrical Life: 100000Mechanical Life: 1000000Protection Level: IP20Pollution Level: 3Altitude: ≤2000mOperating Temperature: -50℃-55℃Humidity: ≤50% at 40℃(no condensation)Storage Temperature: -30℃-70℃Product Features: 1.
