The SIDAC 4EU9932-0AN40-0BA0 is a 3-phase AC filter reactor — a line reactor — rated 150 A continuous with a 166 A maximum, wound for 400 V AC at 50 Hz. The 0.0016 H inductance and 7 % relative throttling factor shape the harmonic profile on the line side of a drive or power converter. The 189 Hz resonant frequency tells you where the filter bank is tuned; the 100 kvar reactive power rating sizes the bank it belongs to.
The 166 A maximum is the short-term overload ceiling — useful for sizing upstream protection and verifying the reactor won't saturate during a motor start or drive transient. The 7 % throttling factor means the reactor drops about 7 % of line voltage at rated current, which is the standard impedance for most 400 V drive input circuits. The IP00 enclosure means it's a bare core-and-coil assembly — no finger protection, no drip shield.
Deployment context
This is a panel-mount component — the IP00 rating and screw/flat-type terminals mean it lands inside a cabinet, not on the wall. Typical placement is between the line supply and the drive input, or between the drive output and the motor, to limit harmonic distortion and reduce dv/dt stress on motor windings. The 3-phase, 400 V, 50 Hz spec matches standard European industrial mains. Thermal class H insulation gives headroom for installations where the cabinet ambient runs above 40 °C, provided the reactor is derated per the manufacturer's curve.
