Rated 57.9 A continuous with a 64.3 A maximum, it is sized for a 400 V, 50 Hz supply. The 7 % relative throttling factor means it introduces 7 % impedance at rated current, which is the typical sweet spot for variable-frequency drive input filtering without excessive voltage drop. Enclosure is IP00 — open frame. Mounting dimensions: 0.187 m deep, 0.27 m wide, 0.248 m high. Thermal class H (IEC 60085) means the insulation system withstands 180 °C hot-spot temperature — a safety margin for reactors running near rated current in a 40 °C ambient. The 209.5 W power loss at full load must be vented; do not bury this unit against heat-sensitive components. Inductance is 0.00096 H with 7 % throttling factor at 50 Hz. For a 400 V drive, 7 % impedance limits inrush and reduces harmonics. Reactive power of the filter bank is rated at 40 kvar. That is the reactive power the reactor absorbs at rated current and voltage. If you are sizing a power-factor correction bank, account for this absorption — the reactor looks inductive to the mains. Resonant frequency is 189 Hz. This is the self-resonance of the reactor itself. Keep the drive's switching frequency and any parallel capacitance away from this point to avoid parallel resonance that could amplify harmonics.","metaTitle":"Siemens SIDAC 4EU2732-7MA08-0AA0 Filter Reactor, 57.9A, 400V","metaDescription":"Siemens SIDAC 4EU2732-7MA08-0AA0 filter reactor, 3-phase, 57.9 A rated, 400 V, 50 Hz, 7% throttling, IP00.
