Voltage Protector 110V 220V, 63A Adjustable Smart Circuit Breaker(4PCS) Real-time voltage & current display, High/Low Voltage Cutoff and Overcurrent Protection

Wide Voltage Range and High
Current Capacity: Supports AC voltages ranging from 110V to 220V, with a maximum rated current of 63A. Extremely suitable for protecting high-power household and office appliances, including air conditioners, refrigerators, washing machines, water heaters, and other voltage-sensitive electronic devices.
Real-time LCD Display: Allows for clear and immediate monitoring of the voltage and current of the power supply, with high measurement accuracy (relative error less than 1%, absolute error ±5V). You can precisely know what has happened to the power supply without having to guess.
Adjustable overvoltage/undervoltage protection: When the voltage exceeds the safety limit, the fully customizable voltage threshold will automatically cut off the power supply to prevent damage to expensive appliances. Set your own protection parameters according to the specific requirements of your equipment.
Intelligent delay and overcurrent protection: Adjustable trip delay ( 0.1 - 10 seconds) can prevent nuisance tripping during brief voltage fluctuations. Customizable overcurrent protection (1A - 63A) adds an additional layer of safety protection. With configurable delay (1 - 999 seconds), automatic reset ensures safe power restoration.
Simple DIN rail installation: The standard 35mm DIN rail can be installed in the design allowing for quick and safe installation in the distribution panel. No special tools are required - the simple snap-on installation saves time and effort. Compact size (9 cm x 7.6 cm x 4.2 cm) is suitable for most distribution boxes
