The SA 0440 surge protective device is designed to protect three-phase electrical systems from lightning surges and transient overvoltages. Installed at distribution board level, it diverts excess surge energy away from electrical installations and connected equipment, reducing the risk of damage and system failure. Built in compliance with IEC standards, it provides reliable surge protection for residential, commercial, and light industrial power systems.

Applications:

  • Distribution Boards: Protects three-phase incoming power supply
  • Commercial Buildings: Offices, shops, and commercial installations
  • Residential Systems: Three-phase household electrical setups
  • Light Industrial Use: Protects equipment and control panels.
