1. Product Overview

The Tuya WiFi smart voltage current protector is an all-in-one IoT power protection device that combines power parameter monitoring, remote switch control and multi-dimensional electrical safety protection into a single DIN rail module. Designed for single-phase AC 230V low voltage circuits, it integrates WiFi wireless communication to connect with the Tuya Smart mobile application.

Users can remotely view real-time voltage, load current, cumulative energy consumption, residual leakage current data via mobile phones, remotely cut or restore power, and receive instant fault alarm push notifications. Equipped with a front LCD display and four physical setting buttons, all protection thresholds (overvoltage, undervoltage, overload, leakage) can be freely calibrated on-site without software. It effectively prevents electric shock, wire burnout and equipment damage, perfect for smart home, rental property management, commercial retail and small industrial equipment power control.

2. Core Product Features

1. Tuya WiFi IoT Remote Mobile Control

  • Built-in 2.4G WiFi module, quick pairing with Tuya Smart / Smart Life App
  • Real-time remote data viewing: voltage, current, power, kWh energy, leakage current, temperature
  • One-click remote switch on/off load power anywhere with mobile phone
  • Instant mobile push alarm for overvoltage, overload, leakage, undervoltage faults
  • Support timer switching, power consumption statistics, historical running data storage

2. All-Round Multi-Fault Safety Protection

Integrated 4 core protection functions with fully adjustable trip thresholds:
  1. Overvoltage protection: Auto trip when mains voltage exceeds preset upper limit
  2. Undervoltage protection: Auto cut-off power when grid voltage drops below lower threshold
  3. Overload overcurrent protection: Thermal trip under long-time excess load to avoid cable overheating
  4. Residual earth leakage protection: Fast trip when leakage current exceeds setting, prevent electric shock hazards

3. Front LCD Display & Physical Setting Buttons

  • Small LCD screen displays real-time running parameters and fault codes clearly
  • Four independent blue operation buttons (Up / Down / SET / Reset) for local parameter configuration
  • No need for mobile phone debugging when adjusting protection values on-site, convenient for installation engineers

4. Standard 2P Full L+N Disconnect Design

2-pole structure cuts off both Live (L) and Neutral (N) lines simultaneously when tripping, forming full visible isolation gap to eliminate residual live-line risks during circuit maintenance. Clear IN (power input) and OUT (load output) terminal labels to avoid wiring mistakes.

5. Compact DIN Rail Modular Structure

Single module width, directly snap onto universal 35mm DIN rail inside distribution cabinets, saves cabinet layout space. High-strength flame-retardant insulated plastic housing with anti-interference internal circuit, stable operation in complex electromagnetic indoor environments.

6. Independent Pulse Alarm Function

Built-in pulse signal prompt, local buzzer reminder when fault occurs, can mute alarm manually on the device or via mobile APP, convenient for unattended rental house and remote monitoring scenes.

3. Working Conditions

This Tuya WiFi smart power protector maintains stable monitoring and protection performance under standard indoor environments:
  1. Ambient operating temperature: -10℃ ~ +55℃
  2. Protection Grade: IP20, only installed inside fully enclosed indoor distribution cabinets; not for outdoor splash, humid or heavy dust open areas
  3. Surrounding atmosphere: Free of corrosive gas, flammable dust and conductive metal particles
  4. Altitude: Full rated performance below 2000 meters above sea level
  5. Vibration resistance: Tolerate mild indoor mechanical vibration, avoid continuous strong impact
  6. Humidity: Relative humidity ≤85%, no condensation on the device surface

6. Frequently Asked Questions (FAQ)

1. Does this device support 5G WiFi?

Only 2.4GHz WiFi network is supported; 5GHz WiFi signals cannot be recognized for pairing. Please connect your mobile phone to a 2.4G router during configuration.

2. Can I remotely turn off power after a leakage fault occurs?

Yes. Once leakage, overvoltage or overload triggers a trip, the device sends an alarm notification to your mobile APP, and you can remotely restore power after troubleshooting the circuit.

3. Are all protection thresholds adjustable?

All protection values (overvoltage limit, undervoltage limit, overload current, leakage trip current) can be adjusted either via the front physical buttons or within the Tuya mobile APP.

4. Can this protector record cumulative electricity consumption?

Yes, it continuously records real-time and total cumulative kWh power consumption data, which can be viewed on both the LCD screen and Tuya APP with historical power usage curves.

5. Is outdoor installation allowed?

No, IP20 protection grade only supports installation inside sealed indoor distribution cabinets. Outdoor rain and moisture will damage the WiFi communication module and internal circuit board.

6. Can multiple mobile phones log in to monitor one protector?

You can share device access permission to multiple family or administrator accounts within the Tuya APP, enabling simultaneous remote viewing and control by multiple users.
