What this filter reactor does on the line
The SIDAC 4EU9932-0AG00-0BA0 is a 3-phase AC filter reactor rated for 400 V operating voltage at 50 Hz. Its rated current is 69.7 A, with a maximum continuous current of 77.4 A — the headroom handles moderate overloads without saturating the core. The 0.0017 H inductance and 14% relative throttling factor mean it presents enough impedance to limit harmonic currents and reduce voltage notching from drives or rectifiers. The resonant frequency sits at 134 Hz, well above the 50 Hz fundamental, so it won't accidentally resonate with the line frequency under normal conditions.
Connections are via flat connector / screw-type terminals, which are standard for power-distribution wiring in industrial control panels. Thermal class H per IEC 60085 means the winding insulation withstands a 180 °C hot-spot temperature, adequate for the 40 °C ambient rating with natural convection cooling inside a ventilated enclosure.
The manufacturer classifies this part at a mature lifecycle stage — it is not in active phase-in or phase-out, but it is also not a current-promotion item. No official successor order code has been published, so the BOM line should be treated as a single-source item unless a parametric substitute is validated.
