Supplier's note

  1. Technical Breakthroughs:

    • BCD Curve Coverage: The MW series’ multi-curve capability (B/C/D) enables precise protection for mixed loads.
    • PA66 Material: Enhances thermal endurance, outperforming standard plastics in high-temperature environments.
    • 10kA Breaking Capacity: Exceeds industry benchmarks for residential/commercial safety standards.

  2. Version Selection Guide:

    • Base Model: Ideal for residential circuits (e.g., lighting, outlets) where 20A suffices.
    • Advanced Model: Suitable for light commercial use (e.g., HVAC systems) requiring higher current and IP30 dust resistance.
    • Pro Model: Designed for industrial applications with heavy loads (e.g., motors) and demanding environments. Its IP40 rating and expanded curves (Z/K) provide unmatched versatility.

*Pro Model breaking capacity is 50% higher than the Base Model, ensuring superior fault protection.
