Schneider Electric VW3A4706 EMC noise suppression filter for frequency converters 100 A content_copy

Three-phase supply voltage 200-240 V 50 Hz. EMC radio interference suppression filter, for frequency converter, for ATV630D18M3 - D22M3 converter, category C3, 100 m. Filter_rated current 13.9 mA. The max. lengths are only examples, as they vary according to the stray capacitance of the motors and cables used. For motors connected in parallel, the length of all cables must be taken into account. The values indicated depend on the nominal switching frequency of the converter. This frequency depends on the nominal size of the converter. Max. length of the shielded cable according to IEC/EN 61800-3 category C2 (50m). Max. length of the shielded cable according to IEC/EN 61800-3 category C3. For more stringent requirements, additional EMC input filters can be used. They reduce conducted emissions to values below category C1, C2 or C3 of the IEC/EN 61800-3 standard. These additional filters can only be used in TN networks (connection to neutral conductor) or TT networks (connection of the neutral conductor to earth). According to the IEC/EN 61800-3 standard, Appendix D2.1, filters in IT systems (isolated or neutral earthed impedance) can result in continuous insulation monitoring only taking place in random operation.
