It's a line-reactor / choke intended to suppress harmonics and limit inrush current on the line side of variable-frequency drives, UPS systems, or other non-linear loads. The 7 % relative throttling factor means the reactor's impedance is 7 % of the base load impedance at rated current — a common value for drive input reactors that keeps total harmonic distortion (THD) manageable without excessive voltage drop. The 77.7 A rated current and 51 kvar reactive power tell you the reactor is sized for a 400 V, 50 Hz system drawing roughly 77 A per phase. That's a 55–60 kW drive at typical power factor. The 0.76 mH inductance and 189 Hz resonant frequency mean the reactor is tuned to attenuate the 5th harmonic (250 Hz) and above — standard for 6-pulse rectifier front ends. Dimensions are 0.27 m wide × 0.248 m tall × 0.187 m deep. The flat-type / screw terminals accept lug or busbar connections for the main circuit. Mounting is inside a panel or enclosure; the IP00 rating requires the cabinet to provide the environmental seal. Power loss is 232 W at full load — account for that heat in the enclosure's thermal budget.","metaTitle":"SIDAC 4EU2732-0BE08-0AA0 Filter Reactor, 77.7A, 3-Phase","metaDescription":"SIDAC 4EU2732-0BE08-0AA0 3-phase filter reactor, 77.7A rated, 400V, 50Hz, 7% throttling, 51 kvar, IP00.
