Supplier's note

  1. Technical Breakthroughs:

    • Transparent Polycarbonate Body: With visual inspection capability, you can identify loose connections 20% faster than traditional opaque models.
    • Spring-Loaded Brass Contacts: Deliver 15% lower contact resistance compared to fixed designs, ensuring stable power flow.
    • Modular Scalability: Supports 50% more contacts in the Pro Model, enabling complex system integration.

  2. Version Selection Guide:

    • Base Model: Best for standard power distribution in small-to-medium systems (e.g., residential panels). Its 100A rating meets most commercial needs.
    • Advanced Model: Ideal for industrial applications requiring expanded contact capacity (e.g., manufacturing plants). Silver-plated brass enhances durability in corrosive environments.
    • Pro Model: Designed for high-current scenarios (e.g., renewable energy grids). The 120A rating and gold-plated contacts triple the longevity in harsh conditions.

*Pro Model’s 120A rating exceeds industry benchmarks by 20%.
**Gold-plated contacts reduce oxidation risks by 40% compared to standard brass.
