When it may not be suitable

This device is specifically designed for TNS systems and may not be compatible with other earthing arrangements such as TT or IT systems without appropriate modifications or additional components. It is not intended for use in high-voltage industrial transmission lines or environments where the surge current exceeds the specified discharge capacity of the device.

How to use

The installation of the surge arrester should be performed by a qualified electrician in accordance with local electrical regulations and safety standards. The device is typically mounted on a standard DIN rail within the main distribution board. Ensure that the connections are secure and that the cross-section of the connecting cables meets the requirements for the specific installation environment to ensure optimal performance and safety.

What to consider before purchase

  • Verify that your electrical system is a TNS configuration
  • Ensure there is sufficient space in your distribution board for a 4-pole device
  • Check the local lightning protection requirements for your building type
  • Confirm that the installation is performed by a certified professional

Usage recommendations

Regularly inspect the status indicator on the device to ensure it remains in operational condition. If the indicator shows a fault, the surge arrester should be replaced immediately to maintain continuous protection for your electrical equipment.
