The Siemens SIDAC 4EU3632-0FK00-0AA0 is a 3-phase filter reactor rated for 245 A continuous (258 A maximum) at 400 V AC, 50 Hz. Its 0.22 mH inductance and 5.67 % relative throttling factor are sized for harmonic mitigation on a 12.4 kvar capacitor bank. Thermal class H (180 °C) insulation gives headroom for sustained load at a 40 °C ambient, with 429 W of full-load heat that must be ventilated.
Dimensions are 0.35 m wide by 0.321 m tall by 0.227 m deep — a substantial block that needs a dedicated footprint in the cabinet. Main circuit connections use flat connectors or screw-type terminals, typical for bolted bus-bar or cable-lug termination. The 429 W of heat dissipation at full rating requires forced air or a properly sized cabinet volume; thermal class H insulation allows a 40 °C ambient without derating.
The resonant frequency is 210 Hz — well above the 50 Hz fundamental, so the filter targets the 5th and 7th harmonic orders typical of 6-pulse drives. Reactive power of the filter bank is rated at 12.4 kvar. This reactor is designed to EN 61558-2-20 (safety of transformers, reactors, and power supply units).
