EMC/RFI Filter for Installations with Residual Current Device (RCD)

Full functionality with RCDs according to IEC 61008 and new VDE 0664-110*
Compatible with 30 mA RCDs up to 30 m motor cable for electric shock protection according to IEC 61008
Compatible with 300 mA RCDs up to 100 m motor cable for fire protection according to IEC 60364-4-42 (VDE 0100-482)

Features and Benefits

Innovative low-leakage current filter with same smallest dimensions as FN 3258

Significant reduction of leakage and ground currents caused by long motor cables

Prevents unwanted fault shut-downs from RCDs in machines and process automation equipment

Patented filter design avoiding early saturation and ringing effects

Excellent attenuation compliant with: C1 limits EN 61800-3 with 30 meter motor cable and 30 mA RCD (electric shock protection)**

C2 limits EN 61800-3 with 100 meter motor cable and 300 mA RCD (fire protection)
