ILF 4P 250/400
Low Voltage Surge Protection Device
ZOTUPFILTER
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 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 (2011-03) and Type T1, T2 and T3 according to
EN 61643-11(2012-10); - 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.
