Line reactor for 400 V AC drives — 83 A continuous, 92.2 A peak
The Siemens SIDAC 4EU2732-3MB08-0AA0 is a 3-phase filter reactor rated for 83 A continuous (92.2 A maximum) at 400 V AC, 60 Hz. The 0.51 mH inductance with a 5.67% relative throttling factor places it squarely in the line-reactor class for variable-frequency drive input circuits — it smooths current harmonics and limits di/dt on the DC bus. The 50 kvar reactive power rating tells you the reactive compensation it can handle; the 252 Hz resonant frequency means it's tuned to suppress harmonics around the 5th (300 Hz at 60 Hz fundamental), which is the dominant harmonic from a 6-pulse rectifier.
Sizing and fit — what the 83 A / 92.2 A split means
The 83 A rated value is the continuous thermal current under the rated ambient of 40 °C. The 92.2 A maximum is the overload ceiling before the Class H insulation starts degrading.
Panel integration — dimensions and terminals
The reactor measures 0.187 m deep by 0.27 m wide by 0.248 m tall. The main circuit connections are flat connector / screw-type terminals.
