2.6.1 Footprint mains filters and footprint combination mains filters
The footprint (UB)- mains filters SK LFx-4x0/xx-F and the combined footprint combination mains
filters SK NHD-480/xx-F differ by the additional integrated mains input choke. The following tables list
and compare the various footprint mains filters allocated to each of the performance levels. Both
mains filters come in protection class IP20 and can be fitted as footprint and also as book size
components. Mains connection to the mains filters occurs with screw terminals. Depending on the
cable type (shielded or unshielded) and the length of the motor cable, both footprint mains filters
feature a radio interference suppression level Class B or C1 with a maximum motor cable length of
50 m and a shielded cable. For a maximum motor cable length of 100 m and shielded motor cable,
both footprint mains filters comply with EMC limit value classes A or C2.
