The SIDAC 4EU2732-0EA68-4EA0 is a 3-phase filter reactor — a line reactor — rated for 35 A continuous with a 38.5 A maximum, at 400 V AC, 50 Hz. The 14% relative throttling factor means it drops about 14% of line voltage at rated current, which is the typical range for harmonic mitigation and motor-drive protection. The 25 kvar reactive power rating tells you the reactor's reactive power handling at rated voltage — useful when sizing for power-factor correction banks or drive input circuits. The 0.0033 H inductance combined with the 134 Hz resonant frequency means this reactor is tuned to avoid resonance at the 2nd and 3rd harmonic of a 50 Hz line — it's not a notch filter, but it won't amplify those common harmonics either. Thermal class H insulation (180 °C rated) gives headroom in warm cabinets; the 40 °C ambient rating is the baseline, and class H lets it run hotter without derating prematurely.
IP00 means no enclosure — this is a panel-mount component for indoor, clean, dry electrical rooms. Mount it on a sub-panel or chassis; the flat connector / screw-type terminals accept cable lugs or bus bars. Dimensions are 0.27 m wide × 0.248 m tall × 0.187 m deep — allow clearance around the core for airflow and magnetic field.
