Key Features
- Real-Time Three-Phase Monitoring: Continuously tracks voltage, current, power, energy consumption (kWh), frequency, and power factor across all three phases. Data is displayed clearly on a color LCD screen for at-a-glance readings.
- Comprehensive Electrical Protection: Built-in overvoltage, undervoltage, overcurrent, undercurrent, leakage current, voltage imbalance, current imbalance, phase loss, phase sequence, high-temperature, and time-delay protection — all fully adjustable to suit your specific installation requirements.
- WiFi App Remote Control: Connects via WiFi to the Tuya or Smart Life App, enabling remote monitoring of power status, viewing of operating data, and adjustment of protection settings from anywhere — ideal for smarter, more flexible energy management.
- Fault Logging & Timed Switch: Automatically logs faults including overvoltage/undervoltage, overcurrent/undercurrent, leakage current, imbalance, phase loss, and phase sequence events. The built-in timed switch function enables scheduled power control for efficient energy use.
- Auto-Reclosing Function: After a protective trip, the device supports auto-reclosing to restore power automatically once conditions return to normal — reducing downtime without manual intervention.
- Easy DIN Rail Installation: Mounts directly onto standard 35mm DIN rails. Compact form factor (approx. 86.5 × 74 × 50 mm) fits neatly into distribution boxes and electrical panels. Installation must be performed by a qualified electrician.
