Class I+II Lightning current Surge Protective Devices for Three-phase TN-S Power Supply System
Summary
For installation at LPZ 0A-1 or high, protecting low voltage equipment against lightning and surge damages. Specially designed for TN-S system. Applied in SPD Class Ⅰ (Class B) for various power supply system of lightning current surge protection. Designed according to GB 18802.1/IEC 61643-11.
Hightlight Features
• Combined lightning current arrester for 3-phase TN-S ( “4+0” circuit) system, Pluggable Iimp(10/350μs):25kA,In(8/20μs):50kA, Imax(8/20μs):75kA, Iimp(10/350μs)total 100kA.
• Adopt hermetical GDT technology, high follow current extinguishing capacity.
• Extremely low voltage protection level.
• Double thermal disconnector devices, providing more reliable protection.
• Green window will change to red when fault occurs, also provide remote alarm terminal at the same time.
