Product Description

Electronic circuit breakers stand out for their key advantages. They provide precise protection, leveraging advanced sensors and microprocessors to detect overloads, short - circuits, and other anomalies with high accuracy, ensuring quick and targeted tripping. Unlike traditional breakers, they offer flexible settings, allowing users to adjust current limits, trip times, and protection modes via digital interfaces to fit diverse electrical systems.

 

Moreover, they enable remote monitoring and control, supporting integration with smart grids or building management systems, so operators can check status, receive alerts, and even operate breakers remotely. Additionally, their compact design and high reliability make them space - saving and durable, reducing maintenance costs and downtime.

 

Key Parameters

1. Rated Voltage
   • Typically covers ranges like 120V, 240V (single-phase) or 208V-480V (three-phase), suitable for different power systems.
2. Rated Current
   • Common ratings: 15A, 20A, 30A, up to 200A+ for various load requirements.
3. Interrupting Capacity
   • Measures the maximum fault current it can safely interrupt (e.g., 10 kA, 22 kA).
4. Protection Functions
   • Overload protection, short-circuit protection, ground fault protection (optional for some models).
5. Trip Characteristics
   • Thermal-magnetic trip (standard) or electronic trip with adjustable settings (e.g., instantaneous, short-delay, long-delay trips).
6. Communication Interface
   • Supports protocols like Modbus, BACnet, or Ethernet for remote monitoring and integration with smart systems.
7. Operating Temperature
   • Typically -20°C to +60°C (-4°F to 140°F) for reliable performance in diverse environments.
8. Enclosure Rating
   • Often meets IP20, IP44, or higher standards for dust and moisture protection.
9. Certifications
   • Compliant with standards like UL 489 (USA), IEC 60898 (Europe), or GB 10963 (China).
10. Mounting Type
    • Plug-in (for panel boards) or bolt-on (for industrial applications).
11. Number of Poles
    • 1P (single-phase), 2P/3P (three-phase) options.
12. Energy Efficiency
    • Low power consumption in standby mode (e.g., <1W).
