Supplier's note

  1. Technical Breakthroughs:

    • Bimetallic Strip Sensitivity: 20% faster thermal response than industry benchmarks ensures quicker overload detection.
    • Corrosion-Resistant Housing: Stainless steel terminals extend lifespan in corrosive environments.
    • Low-Leakage Design: 99.9% isolation efficiency minimizes energy waste.

  2. Version Selection Guide:

    • Base Model: Ideal for standard industrial motors (e.g., HVAC fans) requiring 80A protection.
    • Advanced Model: Suitable for heavy-duty pumps or robotics needing faster reset times and IP54 protection.
    • Pro Model: Best for marine or outdoor equipment (e.g., offshore machinery) with extreme current demands and IP67 waterproofing.

With the Pro Model’s 6-second thermal response, you can prevent catastrophic failures in high-power systems. Pair its IP67 rating with outdoor applications to ensure uninterrupted operation in rain or dust.
