Supplier's note

  1. Technical Breakthroughs:

    • Adjustable BCD Curves: The ability to switch between D, B, and C curves allows one device to protect diverse loads (e.g., motors, lighting).
    • 6kA Breaking Capacity: Exceeds industry benchmarks, ensuring safe interruption of high fault currents.
    • Dual AC/DC Compatibility: Enables use in both traditional and renewable energy systems (e.g., solar inverters).

  2. Version Selection Guide:

    • Base Model: Ideal for standard residential/commercial circuits (e.g., lighting, HVAC).
    • Advanced Model: Suitable for industrial machinery or high-current applications requiring enhanced breaking capacity.
    • Pro Model: Best for critical infrastructure (e.g., data centers, mining) needing ultra-high fault protection and adaptive curves.

Example: With the Pro Model’s 10kA breaking capacity, you can safely protect high-voltage industrial systems against short circuits. Its adaptive curve ensures minimal downtime by distinguishing between harmless surges and dangerous faults.
