What this reactor does on the line
The Siemens SIDAC 4EU3632-3MA08-0AA0 is a 3-phase filter reactor rated 158 A continuous with a 175 A maximum, designed for 400 V AC 50 Hz line operation. Its 0.00031 H inductance at a 5.67% relative throttling factor shapes the harmonic profile and limits inrush on drives or power-factor-correction banks. The 210 Hz resonant frequency places the filter's anti-resonance below the 5th harmonic (250 Hz at 50 Hz fundamental), so it blocks the dominant VSD harmonic while passing fundamental power. This is a standard detuned filter design for industrial distribution — you see these ahead of capacitor banks or at the input of 6-pulse drives.
Mounting and enclosure reality
The 0.35 m width, 0.321 m height, and 0.227 m depth define the footprint; plan for clearance around the screw/flat-type terminals on the main circuit connections.
