The SIDAC 4EU2452-0AD00-4BA0 is a 3-phase AC output reactor (output choke) rated for a maximum continuous current of 111A at a rated frequency of 4000Hz, with an inductance of 0.07mH. It sits between the drive output and the motor cable to limit the rate of voltage rise (dV/dt) and reduce capacitive charging currents in long cable runs — critical on a line where reflected-wave overvoltage can punch through motor insulation. The 111A rating means it handles a motor load drawing up to that current without saturating the core; the 4000Hz switching frequency matches modern IGBT drives running fast carrier frequencies, so the reactor's impedance stays effective at the switching harmonics that cause the most motor stress.
Thermal and environmental limits
Rated for a 40°C ambient with thermal class H insulation (180°C hot-spot) per IEC 60085. The IP00 enclosure means it is an open-frame component — it needs a clean, dry panel or cabinet; no washdown, no dust. The flat-type terminals accept busbar or cable lugs, typical for the current level. Dimensions: 0.22m wide, 0.21m high, 0.13m deep — plan panel space accordingly.
