The SIDAC 4EU3651-0BA00-4CA0 is a 3-phase output reactor (output choke) rated for 105 A continuous at 400 VAC, with a switching frequency of 7 kHz and an inductance of 0.56 mH. It sits between a variable-frequency drive and the motor to limit the rate of voltage rise (dV/dt) and reduce reflected-wave peaks on long cable runs — protecting the motor winding insulation from premature failure. Rated ambient temperature is 40 °C, and the thermal class is H (180 °C) per IEC 60085, meaning the winding insulation can handle sustained high-temperature operation typical of continuous-duty drive applications.
The enclosure footprint is 0.35 m wide by 0.32 m tall by 0.22 m deep — a substantial block that needs dedicated panel space or a separate mounting plate, not a DIN-rail clip. Protection class is IP00, so it requires installation inside a cabinet or enclosure that provides the environmental seal — no washdown or dust-exposed placement. Main circuit connections use flat-type terminals, which call for ring or fork lugs and a torque wrench; spring-cage or screw-clamp terminal blocks won't mate directly.
The lifecycle stage is marked mature, indicating the design is stable and not in active phase-out, but volume may shift to replacement series over time.
