Modern, complete combined (hybrid) surge arresters with advanced design:
• spark-gap technology used, ensuring protection of installations and devices against threats from direct or close lightning discharges, induced lightning overvoltages and switching overvoltages,
• technical parameters corresponding to the operation of two-stage protection (1+2, formerly B+C),
• energy coordination enabling three-level protection for end devices within
≤ 5m,
• meeting the requirements of III and IV class of lightning protection,
• voltage protection level ≤ 1.5kV,
• surge current resistance up to 50 kA,
• follow current extinguishing capacity up to 50 kAeff,
• selectivity with fuses with low rated currents (no unnecessary tripping of the fuse link)
• intended for various types of networks (TN-S, TN-C, TT).
