Applicable scenarios

Unique advantages

  • Surge Protection: Handles voltage surges up to 40kA (8/20μs) with a lightning-fast 25ns response time, safeguarding electrical systems from lightning strikes and power fluctuations.
  • Modular Control: Four independent poles with manual O-F switches enable precise circuit management, testing, and maintenance for each phase in multi-phase systems.

Key features

  • 1. Robust Material Technology for Enhanced Durability

    • With a corrosion-resistant plastic housing and high-current capacity (Imax: 40kA), you can ensure reliable protection against environmental stress and extreme voltage surges.

  • 2. User-Friendly Interactive Design for Easy Maintenance

    • With four independent manual switches (O-F), you can quickly test and maintain each pole’s functionality, simplifying troubleshooting and system upkeep.

  • 3. Ultra-Fast Response Time for Superior Surge Protection

    • With a 25ns response time—50% faster than standard SPDs*—you can neutralize surges instantly, safeguarding sensitive electronics like servers and appliances.

  • 4. Versatile 4-Pole Design for Commercial/Industrial Use

    • With a 4-pole configuration for 3-phase systems, you can protect large-scale installations (e.g., data centers, factories) where continuous power stability is critical.

  • 5. Compliance with International Environmental Standards

    • With an IP20 rating, you can ensure dust and water resistance, meeting global safety standards for outdoor or exposed electrical setups*.
