The Finder surge protection devices are designed as Type 1+2 surge arresters with a high discharge capability and no following current, suitable for single/three-phase systems. These surge arresters safeguard low-voltage applications against overvoltage from direct lightning strikes, induced overvoltage, and switching overvoltage. They are intended for installation at the boundary of LPZ 0 - LPZ 1 zones or higher. Versions equipped with a combination of varistor and high-performance spark gap (GDT) ensure high discharge current, high insulation resistance eliminating leakage current, and no following current, providing comprehensive protection against surges.
