It sits between the variable-frequency drive and the motor cable to limit the rate of voltage rise (dV/dt) and reduce capacitive charging currents in long cable runs — critical for preventing nuisance tripping and motor insulation stress on PWM drives. The 5.3 kHz switching frequency matches the carrier frequency of many modern IGBT drives; if your drive runs a lower carrier (e.g., 2–4 kHz), the reactor still works but the core loss profile shifts. The IP00 open-frame construction means it mounts inside a cabinet, not in a wet or dusty environment — plan for at least 100 mm clearance around the unit for airflow, given the combined 402 W power loss (226 W coil + 176 W iron core at rated load). Class H insulation (180 °C thermal class per IEC 60085) gives headroom for sustained high-ambient operation up to the rated 40 °C ambient without derating. ## Mounting and integration — what fits where The reactor measures 0.3 m wide by 0.26 m tall by 0.21 m deep — a substantial block that needs a backplate or chassis mount, not a DIN rail. Terminals are flat-type connectors for the main circuit, sized for the 85 A rating; plan for lug or bus-bar connections rather than screw-clamp terminals. The IP00 rating means no ingress protection — locate it inside a ventilated cabinet away from conductive dust or dripping water. Given the 402 W total loss, forced-air cooling is advisable if the enclosure is sealed or densely packed.","metaTitle":"Siemens SIDAC 4EU3052-0AN20-4BA0 Output Reactor, 85A, 5.3kHz","metaDescription":"Siemens SIDAC 4EU3052-0AN20-4BA0 output reactor, 3-phase, 85A max, 5.3kHz switching frequency, 0.12mH, IP00.
