Supplier's note

  1. Three Technical Breakthroughs:

    • BCD Curve B: Provides precise overload protection for standard residential/commercial circuits.
    • 4.5kA Breaking Capacity: Safeguards against high fault currents in industrial environments.
    • Dual Voltage Support (48V/415V): Enables seamless integration into low- and medium-voltage DC systems.

  2. Optimal Version Selection:

    • Base Model (50A–100A): Ideal for small-scale applications like home solar setups or telecom equipment.
    • Advanced Model (120A–150A): Suitable for medium industrial loads (e.g., EV charging stations).
    • Pro Model (200A): Designed for high-current systems such as data centers or large-scale renewable energy installations.

With a 4.5kA breaking capacity, you can safely handle high fault currents in industrial environments. The dual voltage capability ensures compatibility with both low-voltage DC systems and robust 415V applications.
