Summary:
For installation at LPZ 0A-1 or higher, protecting low voltage equipment from surge damage. Applied in modular SPD Class I+II (Class B+C) for three-phase TN-S (TNC-S) power supply system. Designed according to IEC 61643-11/EN 61643-11/GB18802.11.
Main Character:
• Combined lightning current arrester for three-phase TN-S ( "4-0" circuit) system
• High discharge capacity, quick response
• Double thermal disconnector devices, providing more reliable protection
• Green windows will change to red when fault and also provide remote alarm control at the same time
