Schurter FMBD EP Two-Stage Three-Phase EMC Filter With Neutral
Chassis Mount | 520/760 VAC | 16–230 A | 2-Stage | With Neutral | Machine Safety | Industrial & Low Leakage
Schurter FMBD EP Two-Stage Three-Phase EMC Filter With Neutral Overview
The Schurter FMBD EP is a two-stage three-phase EMC filter for systems with a neutral conductor (L1, L2, L3, N, PE), rated 16–230 A at 520 VAC or 760 VAC from -40°C to 100°C. It is the four-wire companion to the FMBC EP — both products share the same current range, voltage options, housing sizes and Machine Safety variant structure, the sole differentiator being the inclusion of the neutral conductor. Industrial and low-leakage versions are available (low leakage up to 64 A), with Machine Safety variants (IEC 60204-1) across both types in the 3-138-xxx order series.
