The SIDAC 4EU2532-0AW08-0AA0 is a 3-phase filter reactor rated for 46.7 A continuous with a maximum of 51.9 A, operating at 400 V AC, 50 Hz. The 7 % relative throttling factor means it introduces 7 % impedance at the line frequency, which is the typical value for a line reactor used to limit harmonic currents and smooth voltage notches on a VFD input or a power converter DC bus. The resonant frequency of 189 Hz sits above the 5th harmonic (250 Hz) and below the 7th (350 Hz), so it attenuates lower-order harmonics without creating a parallel resonance at a common harmonic order. Thermal class H (180 °C winding rise) gives it headroom for continuous duty in a 40 °C ambient — the reactor can run hot and still hold its inductance within tolerance.
Integration and mounting notes
The 0.225 m width and 0.21 m height fit a standard sub-panel footprint; the 0.16 m depth leaves room for busbars or cable ducts behind it. Terminals are flat connector / screw-type, so you land ring lugs or fork terminals directly on the studs — no special crimp tool needed.
