ILF 2P ...
Low Voltage Surge Protection Device
ILF 2P is a multimode SPD for indirect lightning effects with integrated interference filter for high frequency disturbancies, typically installed in single phase 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
- 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.
