What this part is and what it does
The Siemens SIDAC 4EU2732-6MA08-0AA0 is a 3-phase filter reactor rated for 63.2 A continuous with a maximum current of 70.2 A, designed for 400 V AC, 50 Hz line applications. It provides 40 kvar of reactive power compensation and a relative throttling factor of 5.67%.
Key ratings and what they mean for fit
The 63.2 A rated current (70.2 A maximum) sets the continuous load the reactor can carry without saturating or overheating — match this to the drive or load's nameplate current, not the breaker size. The 5.67% impedance (relative throttling factor) is a standard value for line reactors: it drops enough voltage to smooth current and reduce harmonic distortion without starving the drive of voltage under load. The 40 kvar reactive power rating tells you the reactor's contribution to power-factor correction at rated conditions. Thermal class H insulation (IEC 60085) means the winding can sustain 180 °C hot-spot temperature — typical for industrial drives in warm cabinets where standard class B or F would derate.
