Supplier's note

1. Technical Breakthroughs:

   • Vacuum Insulation: Eliminates oil, reducing fire hazards and enabling compact designs.
   • Enhanced Interrupting Capacity (Pro Model): Handles 37.5kA faults—50% higher than the base model, critical for heavy industrial loads.
   • Faster Arc Quenching (Pro Model): 1.4ms response time cuts fault duration by 30%, minimizing grid disruption.

2. Optimal Version Selection:

   • Base Model: Ideal for standard substations or commercial grids with predictable load conditions.
   • Advanced Model: Suited for medium-scale industrial plants needing 25% higher fault tolerance than baseline systems.
   • Pro Model: Best for high-demand environments like mining or chemical facilities, where tripled mechanical life and 50% higher interrupting capacity ensure uninterrupted operation.

With the Pro version’s 37.5kA interrupting capacity—50% beyond the base model—you can safely handle extreme fault currents. Paired with its 1.4ms arc quenching speed, this creates a 30% faster recovery time for critical infrastructure.
