63A Smart WiFi Circuit Breaker & Energy Meter for DIN Rail (Tuya)

4-in-1 Protection: Over/Under Voltage, Overload and Leakage with Real-Time Energy Monitoring

The 63A Tuya App WiFi Smart Circuit Earth Leakage Over-Under Voltage Protector Relay Device is a smart protective circuit breaker/relay designed to safeguard single-phase electrical installations up to 63 A. It combines over-voltage, under-voltage, over-current and earth leakage protection with energy monitoring and remote app control using the Tuya Smart or Smart Life platform — ideal for modern homes, offices and light commercial setups.

Key Features:

• Wi-Fi control via app – monitor and manage the device remotely from your smartphone.

• Adjustable undervoltage protection – configurable threshold (e.g., 150 V–190 V).

• Adjustable overvoltage protection – configurable threshold (e.g., 250 V–300 V).

• Adjustable over-current protection – ranges from 1 A to 63 A to protect against overloads.

• Earth leakage detection & protection – detects leakage currents (e.g., 10–99 mA) and cuts power for safety.

• Energy and parameter monitoring – built-in voltage meter, current meter and energy consumption (kWh) meter with wide range.

• Adjustable delay before reconnection – configurable reaction time (e.g., 5 s–90 s) to avoid nuisance tripping.

• Auto-reconnect & memory function – restores power after safe conditions and retains settings after power cut.

Typical Uses:
Perfect for smart electrical panels in homes, offices and small commercial spaces, providing real-time protection, energy insights and remote control for safer, more efficient power management.
