Supplier's note

  1. Technical Breakthroughs:

    • DC Compatibility: Unlike AC-only breakers, this MCCB supports full DC12–500V systems, enabling use in EVs and solar grids.
    • High Current Handling: The Pro model’s 250A rating (30% higher than industry benchmarks) suits heavy-duty industrial applications.
    • Copper Contacts: Reduce resistance by 20% compared to aluminum, ensuring stable performance under load.

  2. Version Selection Guide:

    • Base Model (100A): Ideal for residential solar setups or small EV charging stations where lower power is sufficient.
    • Advanced Model (200A): Suitable for commercial systems like data centers or medium-scale solar farms.
    • Pro Model (250A): Best for industrial plants, large EV charging hubs, or high-voltage battery storage systems requiring triple the standard fault protection.

With the Pro’s 10In tripping threshold, you can safely handle surges in electric vehicle charging stations. Pair its copper contacts with IP20 protection to ensure uninterrupted operation in dusty workshops.
