It provides 7% relative throttling factor and 7500var reactive power, with a resonant frequency of 189Hz. This is the line reactor that sits between your drive and the mains — the 7% impedance is the standard value for harmonic mitigation on a 6-pulse rectifier front end, keeping total harmonic distortion (THD) within typical limits for industrial installations. The 10.9A rated current (12.1A max) tells you the continuous load this reactor can handle at 40°C ambient. For a 3-phase 400V drive, that current corresponds roughly to a 5.5–7.5 kW motor — the reactor must be sized to the drive's input current, not the motor nameplate. The 7% throttling factor means the reactor's impedance at rated frequency is 7% of the load's base impedance; that's the sweet spot for reducing harmonic currents without excessive voltage drop at the DC bus. ## Integration notes Dimensions are 0.178m wide × 0.153m high × 0.12m deep. Mounting is via the core frame — no DIN rail clip; plan for bolting to a backplate or chassis. Thermal class B (130°C) means the insulation system is rated for continuous operation at that temperature; the 40°C ambient rating is the surrounding air, not the reactor surface. At IP00, the reactor has no enclosure — it requires a cabinet with at least IP2X or better to keep fingers and debris out. The 189Hz resonant frequency means this reactor self-resonates well above the 50Hz line frequency and its low-order harmonics (5th = 250Hz, 7th = 350Hz), so it behaves as a pure inductive impedance in the operating band.","metaTitle":"SIDAC 4EP3800-7MS00 Filter Reactor, 3-Phase 400V 50Hz 10.9A","metaDescription":"SIDAC 4EP3800-7MS00 3-phase filter reactor, 400V AC, 50Hz, rated 10.9A (max 12.1A), 7% throttling, 7500var, IP00, screw terminals.
