Product Description
Summary:
For installation at LPZ 0A-1 or higher, protecting low voltage equipment from surge damage. Applied in modular SPD Class I (Class B) for TT (3+1 circuit) and TNS power supply system. Designed according to IEC 61643-1/GB 18802.1.
Main Character:
• 10/350μs, 8/20μs sparkgap, Three-phase lightning surge arrester
• Lightning impulse current withstand max.50kA (10/350μs) L-N, max.100kA (10/350μs) N-PE
• Adopt hermetical GDT technology, high follow current extinguishing capacity
• Extremely low voltage protection level
• Double thermals for parallel or series (V-shape) connection
• Multifunctional connection for conductors and busbar
• Green light indicates functional mode (L-N)
