What this filter reactor does and where it fits
The SIDAC 4EU2532-2MA08-4CA0 is a 3-phase filter reactor rated at 47.4 A continuous with a maximum of 52.6 A, operating at 400 V AC, 50 Hz. Its 0.001 H inductance and 5.67 % relative throttling factor are sized to limit harmonic currents and reduce voltage notching on the line side of a variable-frequency drive or a soft starter. The 30 kvar reactive power rating gives a quick sanity check for the capacitor bank it would pair with in a detuned filter assembly. The resonant frequency sits at 210 Hz, which means it avoids the dominant 5th and 7th harmonic bands (250 Hz and 350 Hz at 50 Hz fundamental) and shifts the parallel resonance below the lowest characteristic harmonic. Thermal class H (180 °C insulation system) per IEC 60085 gives headroom for the 164 W power loss at rated load in a 40 °C ambient. IP00 means it is an open-frame component intended for enclosure mounting inside a panel or cabinet — no touch protection, no drip shield. The flat connector / screw-type terminals accept busbar or cable lugs for the main circuit. UL and CSA recognition per EN 61558-2-20 is noted on the manufacturer's description, covering North American installations that require listed components.
Panel integration notes
Mounting dimensions: 0.225 m wide, 0.21 m tall, 0.16 m deep. The IP00 frame requires clearance from grounded metalwork and other live parts.
