Supplier's note

  1. Technical Breakthroughs:

    • 400A Capacity: Enables safe power distribution for heavy-duty automotive systems.
    • Stainless Steel Terminals: Triple the oxidation resistance of standard copper terminals, extending lifespan in harsh environments.
    • IP67 Compliance (Pro): Waterproof design for marine or outdoor applications.

  2. Version Selection Guide:

    • Base Model: Ideal for standard automotive use (e.g., trucks, SUVs) where 400A suffices.
    • Advanced Model: Choose for high-current needs (e.g., electric vehicle charging systems) with adjustable terminals for custom wiring.
    • Pro Model: Best for extreme conditions (e.g., marine engines, off-road vehicles) where IP67 waterproofing and 600A capacity are critical.

With the Pro’s IP67 rating, you can ensure operation in rain or saltwater environments. The Advanced model’s adjustable terminals simplify installation in compact engine bays. Base models provide cost-effective solutions for routine automotive applications.
