Product Main Features

1. Enhanced Safety & Reliability
Features a Maintenance Safety Lock to ensure personnel safety during repairs. An Independent Power Supply prevents system crashes, ensuring operational stability even during grid fluctuations.
2. High-Precision Monitoring
Offers Class 0.5 accuracy for voltage and current detection, and Class 1.0 accuracy for power metering. It retains all standard Miniature Circuit Breaker (MCB) characteristics while adding smart functionality.
3. Smart Communication & Control
Supports flexible communication options including RS485 (default), Wi-Fi, 4G, RJ45, and Zigbee. Users can configure protection actions (shutdown, alarm, or trip) and utilize the built-in timer switch for energy-saving schedules.
4. Advanced Fault Protection & Analysis
The device provides comprehensive protection against:

  • Neutral-faults (immediate power loss trigger)
  • Load imbalance, phase loss, and phase reversal
  • Over-temperature, over/under voltage, and over-power
  • Short circuits and ground faults

Automatic Fault Analysis identifies causes and logs events for easy troubleshooting.

5. Data Security & Maintenance
Includes power outage protection to store and upload data even after the main circuit is off. Supports multiple remote upgrade modes for convenient maintenance without site visits.
6. Leakage protection setting value
10 / 30 / 50 / 100 / 200 / 300 / 500mA (Configurable)
