** To compile a complete part number, please replace the -.. with the required I/O connection style.
** For surge pulse protection, please add Z (e.g. FN 2090Z-10-06, FN 2090BZ-20-08). The different letters code the used Cy values in the filter type (A = 0.47nF; K = 22nF; L = 33nF; N =
100nF; as the FN2090 is a dual stage filter each letter stands for one stage of Cy)
** Maximum leakage under usual AC operating conditions (acc. IEC 60939-3). Note: if the neutral line is interrupted, worst case leakage could reach twice this level. Leakage current
for DC application is 0 mA
