The 3F480-xxx.260 line filters are suitable for suppressing three-phase devices in residential and industrial environments. In order to achieve a high interference suppression effect, the compact line filters are constructed in two stages. These filters have been developed for high requirements. For example, suppression of drive according to EN61800-3 or other power electronic devices according to EN55011. For the C2 category in the first environment, depending on shielded motor cables up to 50 m can be used. In industrial environments, significantly longer motor cables are possible.
