The SIDAC 4EU2532-0MC08-0AA0 is a 3-phase filter reactor rated 80.4 A continuous (89.4 A maximum) at 220 V AC, 50 Hz, with a reactive power of 30 kvar. Its 0.00039 H inductance and 7 % relative throttling factor are tuned to suppress harmonics from power-factor correction capacitor banks or variable-speed drives, protecting upstream switchgear from resonant overcurrent. Terminals are a combination of flat connectors and screw-type, so the wiring interface matches either busbar or ring-lug connections.
Rated current 80.4 A and maximum 89.4 A: this reactor is sized for a continuous load current up to 80 A, with short-term headroom to 89 A. If your drive or capacitor bank draws 75 A nominal, this reactor has margin; if the load routinely peaks above 89 A, you need a larger frame. The 7 % detuning factor shifts the resonant frequency of the L-C circuit to 189 Hz (the listed resonant frequency), which keeps it away from the 5th and 7th harmonics typical of 6-pulse rectifiers — that is the standard tuning for harmonic mitigation in industrial power systems. Thermal class H (180 °C) insulation means the winding can survive sustained overloads without degrading the varnish, important for reactors mounted inside a warm cabinet at the rated 40 °C ambient.
Physical fit and integration notes
Dimensions: 0.225 m wide × 0.21 m tall × 0.16 m deep. It mounts inside a panel on a subplate or chassis; no DIN-rail clip, so plan for bolted fixing. The IP00 open-frame design means the core and windings are exposed — keep a minimum air gap to adjacent metalwork per the manufacturer's clearance recommendations. Flat connectors accept busbar tabs; screw terminals take ring lugs.
