Schurter FMAD Three-Phase Single-Stage EMC Filter With Neutral
Chassis Mount | 277/480 VAC | 6–550 A | 3-Phase With Neutral | Industrial
Schurter FMAD EMC Filter Overview
The Schurter FMAD is a single-stage three-phase EMC filter for systems with a neutral conductor (L1, L2, L3, N, PE), rated 6–550 A at 277/480 VAC from -25°C to 100°C. The industrial-only range covers a wide current spectrum in screw-clamp metal housings, with conductor cross-sections from 4 mm² (6 A) up to copper bars on the 550 A variant. An optional wire-connected version is available on request. Schurter now recommends the FMAD NEO or FMBD EP for new designs.
