Supplier's note

  1. Three Technical Breakthroughs:

    • Copper Conductive Parts: Enables 225A handling, 20% higher than standard aluminum alternatives.
    • Composite Casing: 30% lighter than metal enclosures while maintaining flame resistance (UL 94 V-0).
    • IP67 Pro Model: Waterproof rating for outdoor or wet environments, exceeding industry standards.

  2. Optimal Version Selection:

    • Base Model: Ideal for standard industrial use (e.g., factories) where cost-efficiency is prioritized.
    • Advanced Model: Suitable for corrosive environments (e.g., chemical plants) with its reinforced material.
    • Pro Model: Best for outdoor applications (e.g., solar farms) needing IP67 protection and UL certification.

With the Pro version’s triple-certified chemical resistance, users can safely manage harsh chemicals while its IP67 rating ensures operation in rain or dust. Pair this with the copper conductors for uninterrupted high-current performance.
