: 1. WIFI INTELLIGENT METERING LEAKAGE PROTECTOR: Binding device under WIFI state, mobile phone remote control unlimited distance, real time display of electricity, current, voltage, leakage, with prepaid function, open a of intelligence 2. MULTIPLE PROTECTION, SET BY YOURSELF: With over current and over load protection, over and under voltage protection, leakage protection electrical power consumption is too large will cause wire heating to fire, overcurrent protection can be cut off in 0.1 seconds to prevent fire, troubleshooting can recover by itself 3. COMPLETE FUNCTIONS: The circuit breaker has the most basic and practical functions, such as WIFI Bluetooth, voice control, APP control, timing control, pre paid recharge, working status display, over current protection, over and under voltage protection, real time display of power, power can be reset, leakage protection, adjustable parameters 4. REAL TIME DATA DISPLAY: Electricity, voltage, current, temperature, leakage value display on the same interface without switching, data is more intuitive, a meter for multi purpose, can completely replace the self compound over and under voltage, electric meter, leakage circuit breaker, reclosing, current limiter, life is more convenient 5. TIMING SETTINGS AND VOICE CONTROL: Through the app timing function, the circuit breaker intelligently controls your connected devices , allowing you to plan ahead for accurate times to automatically turn them on or off, can also be easily controlled by voice, providing more convenience for your smart life.
