Key Features & Highlights

• 4-in-1 Smart Protection System: Fully adjustable protection against over-voltage, under-voltage, overcurrent, residual current (leakage), and high temperatures directly from your smartphone or device screen.

• Real-Time Energy Metering: Track live electrical parameters including Voltage (V), Current (A), Leakage (mA), Active Power (kW), Total Consumption (kWh), and Temperature (°C) via the Tuya Smart or Smart Life app.

• Auto-Reclosing Safety: Automatically restores power after grid fault conditions return to normal. (Safety Note: If tripped 3 consecutive times due to leakage, auto-reclosing locks out until manually cleared).

• Flexible 4-Way Control:

  • App Control: Manage settings and toggle power from anywhere worldwide using Tuya Smart or Smart Life.

  • Voice Control: Hands-free integration with Amazon Alexa, Google Assistant, and Yandex Alice.

  • Timing Schedules: Program custom timers and automation schedules to optimize energy usage and lower power bills.

  • Manual Control: Adjust parameters locally via on-device physical keys without requiring an active Wi-Fi connection.

• High-Power Capacity: Built to handle high loads reliably—rated up to 100A (resistive loads ≤ 13kW, inductive loads ≤ 6kW).
