Applicazione:
For electrical installations.
Suitable for lightning protection of power supply system in areas with high risk of lightning strike (LPZ0B or interface between LPZ0B and LPZ1).
Can handle lightning currents and protect sensitive electronic equipment.
Application-optimized and prewired combined lightning current.
Particularly useful in a high lightning density area where the risk of heavy surge current or even direct strike is high (e.g.: buildings equipped with lightning rods).
Installazione:
During installation, please connect according to the installation schematic diagram.
Power must be cut off during installation, live operation is strictly prohibited, and connecting wires must meet the requirements.
