ecosine passive harmonic filter will be operated within specification. This is particular important in terms of
overload.
Please refer to the following examples:
Example 1:
Power line rating: 400 V, 50 Hz
Drive rating: 380–500 V, 50–60 Hz, 15 kW, 22.5 A, B6-diode rectifier without DC-link choke
Planned rectifier/drive input real power: 15kW (100% of drive rating)
Recommended filter according to the filter selection table FN 3440: Type FN 3440-15-113
Example 2:
Power line rating: 400 V, 50 Hz

Recommended filter according to the filter selection table FN 3452: Type FN 3452-30-113
Oversizing of passive harmonic filters is not recommended because of the inherent lower harmonic mitigation
performance at partial load as well as higher cost, size, and weight.
Please refer to Table 2 - Table 9 to select suitable filters.
