FN 3416 (50 Hz) models of the ECOsine product family represent the very compact “economy line” with a THID performance of ≤10% (with Ldc). They are ideal for non-linear three-phase equipment with B6 rectifier front-end that do not require the industry leading <5% THID performance provided by Schaffner ECOsine FN 3410/12 filters. The performance is still sufficient to comply with EN 61000-3-12 or with IEEE-519 for Isc/IL <50.
