Schurter FMBB EP Two-Stage Single-Phase EMC Filter

Schurter FMBB EP Two-Stage EMC Filter Overview

The Schurter FMBB EP is a two-stage single-phase EMC filter rated 1–36 A at 250 VAC, -40°C to 100°C, delivering excellent conducted-emission attenuation performance – EP denoting “excellent performance.” Nickel-plated steel housings span cases 09 through MF to cover the full current range. Four leakage configurations are available: standard (<6.9 mA), low leakage (<0.15 mA), medical M5 (<0.005 mA) and medical M80 (<0.073 mA), with the medical configurations supporting IEC 60601-1 (1 MOOP / 1 MOPP). The FMBB EP supersedes the FSW and FSS series.

Features: Two-stage topology; ‘EP’ designation indicates excellent attenuation performance

Nickel-plated steel housing; Quick connect 6.3×0.8 mm (≤16 A) or Bolt/nut M4 (20–36 A)

Four leakage versions: standard (<6.9 mA), low leakage (<0.15 mA), M5 (<0.005 mA), M80 (<0.073 mA)
