Supplier's note

  1. Three Technical Breakthroughs:

    • Copper Contacts: Enhance conductivity by 30% compared to aluminum, reducing energy loss in high-load scenarios.
    • 50kA Breaking Capacity (Pro): Triple the industry standard, enabling safe handling of severe short-circuit events in industrial plants.
    • 20ms Trip Time (Pro): 20% faster than traditional MCCBs, minimizing damage to sensitive equipment during faults.

  2. Optimal Version Selection:

    • Base Model: Ideal for small commercial spaces (e.g., retail stores) with standard power demands.
    • Advanced Model: Targets medium-scale facilities (e.g., factories) requiring earth leakage protection in wet zones.
    • Pro Model: Designed for high-risk environments (e.g., data centers, chemical plants) where ultra-fast tripping and arc fault detection are critical. With its 50kA breaking capacity, it safeguards against catastrophic failures that could disrupt operations.
