What this reactor does on a VFD output
The Siemens SIDAC 4EU2432-0EH00-1BA0 is a 3-phase output reactor (output choke) rated for 480 V AC, with a maximum continuous current of 90 A and a rated inductance of 0.31 mH. It is designed to sit between a variable-frequency drive and the motor, smoothing the voltage spikes and reducing the dV/dt that long cable runs can reflect back into the drive output stage. The 2 kHz switching frequency matches the typical IGBT carrier frequency on many PWM drives, so the reactor's core sees the harmonics it's tuned for. The 111 W coil loss and 80 W iron-core loss (191 W total at rated load) mean it will run warm — the Class H insulation (180 °C rated) gives headroom, but the 40 °C ambient rating is the number to watch for enclosure derating.
Fit and mounting — open-frame, panel-mount
This is an IP00 open-frame reactor — no enclosure, no touch protection. It is intended for mounting inside a cabinet, on a backplate or chassis, using the flat-type terminals for the main power connections. The dimensions are 0.22 m wide by 0.21 m tall by 0.13 m deep, so it needs a clear panel footprint of roughly 220 mm × 210 mm, plus bending radius for the cable lugs. The flat connectors are sized for bolted bus-bar or ring-terminal termination, not spring-clamp or screw-cage. Verify the cable lug width matches the terminal pad before committing the panel layout.
