Supplier's note

  1. Technical Breakthroughs:

    • RS485 Modbus RTU Protocol: Enables seamless integration with SCADA systems, offering 20% faster data polling than proprietary protocols.
    • Modular Design: Reduces downtime by 50% during maintenance via plug-and-play components.
    • B-Type Overload Curve: Provides 30% faster tripping for motor-driven equipment compared to standard MCBs.

  2. Version Selection Guide:

    • Base Model: Ideal for standard commercial setups (e.g., office lighting) requiring basic remote monitoring.
    • Advanced Model: Suitable for industrial plants needing higher current (80A) and faster communication speeds.
    • Pro Model: Best for harsh environments (e.g., chemical plants) with IP54 protection and customizable overload profiles.

With the Pro Model’s IP54 rating, you can ensure reliable operation in dusty workshops. Pair its custom curve profile with high-inrush equipment to prevent nuisance tripping. For data centers, the Advanced Model’s 19200 bps communication speeds reduce latency in real-time monitoring systems.
