Supplier's note

  1. Three Technical Breakthroughs:

    • 6kA Breaking Capacity: Outperforms industry benchmarks (typically 5kA) for robust short-circuit protection.
    • BCD Curve C: Enables precise tripping for motor-driven loads, reducing nuisance tripping.
    • EPR Germany Compliance: Meets stringent German safety standards for export-ready solutions.

  2. Optimal Version Selection:

    • Base Model (40A): Ideal for small commercial spaces (e.g., offices) with standard loads.
    • Advanced Model (63A): Suitable for workshops or hotels requiring higher capacity while maintaining EU compliance.
    • Pro Model (100A): Best for industrial facilities or large-scale commercial systems demanding peak performance.

With the Pro Model’s 100A rating, you can handle heavy-duty machinery safely. Pair its 6kA breaking capacity with EPR certification to ensure compliance in regulated markets. For residential use, the Base Model balances cost and reliability.
