Modern, complete combined (hybrid) surge arresters of advanced design:
• applied spark-gap technology, ensuring protection of installations and devices against threats coming 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-stage protection for end devices within
distance ≤ 5m,
• meeting the requirements of III and IV class of lightning protection
• voltage protection level ≤ 1.5 kV,
• resistance to surge current 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)
• designed for different types of networks (TN-S, TN-C, TT).
