ILF 4P is a multimode SPD for indirect lightning effects with integrated interference filter for high frequency disturbancies, typically installed in three phase plus neutral TN-systems close to equipment or machinery, particularly in industrial automation environment, with the following features and benefits:

  • Impulse test classification: Test Class III according to IEC 61643-11 Ed.1 (2011-03) and Type T3 according to
    EN 61643-11(2012-10);
  • Protects electronic equipment (PLC or computers, etc.) from overvoltages due to indirect lightning effects and from other interferences;
  • In case of an SPD failure the protection is disconnected without interrupting the downstream supply. The failure is indicated locally by an optical indicator and via a remote signal contact;
  • It is suitable for installation at LPZ boundaries 2 -3 and higher, in accordance with the lightning protection zones concept and in coordination with other SPDs.
