Supplier's note

  1. Key Technical Breakthroughs:

    • Dual-Voltage Compatibility (220V/380V): Enables seamless integration into global power grids.
    • Copper Contacts: Reduces energy loss by 15% compared to aluminum-based switches.
    • Semicircular Breaker Design: Cuts off arcs 30% faster than traditional breakers, enhancing safety.

  2. Optimal Version Selection:

    • Base Model: Ideal for residential or small-scale industrial use (e.g., home generators or HVAC systems).
    • Advanced Model: Suitable for medium-sized factories or commercial buildings needing 380V support.
    • Pro Model: Designed for heavy-duty applications (e.g., mining equipment or marine systems) requiring IP67 sealing and 440V resilience.

Example: The Pro version’s IP67 rating and 80A capacity enable safe operation in offshore platforms, where saltwater exposure and high currents are common. Pairing its copper contacts with the semicircular breaker ensures zero arc risk during power transitions.
