What this output reactor does on the line
The SIDAC 4EU2732-0AG00-0AA0 is a 3-phase AC output reactor rated for 40 A maximum with an inductance of 0.0003 H (0.3 mH) and a switching frequency range from 0 Hz to 8000 Hz. It sits between the VFD output and the motor leads, smoothing the PWM waveform and limiting the rate of voltage rise (dV/dt) to protect motor winding insulation — especially important on long cable runs or with older motors that lack inverter-duty rating. The 0.3 mH inductance and 39.2 % impedance (per the description) are sized for a 400 V line, so it handles the typical 400 VAC three-phase drive output common in European industrial panels.
Mounting and thermal reality — IP00 means panel builders plan the cooling
The reactor measures 0.27 m wide by 0.24 m tall by 0.18 m deep — that's roughly a 270 mm × 240 mm × 180 mm footprint. It's IP00, so no enclosure protection; it relies on the panel's own air circulation or forced ventilation. The combined power loss is 190 W (60 W from the coil plus 130 W from the iron core) at a rated ambient of 40 °C. That's non-trivial heat to manage inside a sealed cabinet — factor in a fan or a larger enclosure than the footprint alone suggests. Thermal class H (180 °C insulation system) means the windings can take sustained high temperatures, but the surrounding panel components still need clearance. Terminals are flat-type connectors, so expect bus-bar or lug-style wiring rather than cage clamps.
