ILF 4P 250/400 is a multimode SPD for direct and indirect lightning effects with integrated interference filter for high frequency disturbances, typically installed in in three phase plus neutral TN- or TT-systems for the protection of Control Rooms, Data Centers or EDPs, with the following features and benefits.

Impulse test classification: Test Class I, II and III (according to IEC 61643-11 ed.1) and T1, T2 and T3 (according to EN 61643-11/A11);
• Although a special inductor ensures an effective attenuation of high frequency interferences capacity, it has an insignificant energy insertion loss if compared with the equivalent one of an insulation transformer;
• Suitable for protection of electronic equipment in harsh environments where even partial lightning currents are to be expected.
