Schurter FMBD EP 3-Phase AC/DC Filters

Schurter FMBD EP 3-Phase AC/DC Filters are double-stage filters with compact dimensions and high performance for three phases with neutral line systems. These filters feature screw terminals and a metal flange that provides an excellent earth connection when screwed to the chassis. Operating within a -40°C to +100°C temperature range, the filters are designed for currents from 16A to 230A (at +50°C, ambient) with leakage currents less than 4mA. The FMBD EP 3-Phase AC/DC Filters are ideally suited for space-constrained conditions in high EMC emission applications, including machine systems for automatic production, motor drives, and industrial plant machinery. These filters are also ideal replacements for Schurter FMBD and FMBD NEO filters.
