What this reactor does in a drive cabinet
The Siemens SIDAC 4EU2732-0AK00-1BA0 is a 3-phase output reactor rated for 480V AC, 200A maximum current, with an inductance of 0.2 mH. It sits between the drive output and the motor leads, smoothing the voltage spikes from the IGBT switching — the 2 kHz rated switching frequency tells you it's matched to the pulse pattern of a standard PWM drive, not a high-frequency SiC inverter. That 0.2 mH is enough to limit the dV/dt on a long motor cable run, protecting the winding insulation from reflected wave damage.
Mounting and thermal reality — IP00 means it's a cabinet part
The 0.27 m width and 0.24 m height give you the footprint for DIN-rail or baseplate mounting; the 0.18 m depth tells you how far it projects from the backplane. Class H insulation (200 °C rated) means the core and windings can run hot without degrading the varnish — useful when the reactor is packed tight in a cabinet with other heat sources. Ambient rated at 40 °C; if your panel ambient pushes higher, expect some derating on the 200 A figure.
