The Siemens SIDAC 4EU3632-5MA08-0AA0 is a 3-phase filter reactor — a line reactor with a specific detuning ratio — designed to sit between a variable-frequency drive and the mains, or in a harmonic-filter bank, to suppress current harmonics and limit inrush. It's rated for a continuous 83.1 A with a maximum of 92.3 A, on a 400 V, 50 Hz supply, and delivers 60 kvar of reactive power. The 14% relative throttling factor (p=14%) and 1.4 mH inductance are tuned to a 134 Hz resonant frequency, which means it's typically used in a detuned filter bank to block the 5th and 7th harmonics from propagating back onto the line.
The 83.1 A rated current and 92.3 A maximum set the thermal limit for continuous motor or drive load. If your drive's input current exceeds 92.3 A at full load, this reactor will saturate or overheat — size up. The 400 V, 50 Hz rating is standard for European industrial mains; it will not work on a 480 V, 60 Hz line without derating the core. The 365 W power loss at rated load means the reactor dissipates that heat into the panel — IP00 open-frame construction (no enclosure) requires free air circulation or forced ventilation in the cabinet. The 0.227 m depth, 0.35 m width, and 0.321 m height define the footprint; it mounts via the flat-type screw terminals on the main circuit, not on a DIN rail. Class H insulation (180 °C thermal class per IEC 60085) gives headroom for a 40 °C ambient — the reactor can run hot without winding failure, but the surrounding components must tolerate the radiated heat.
