What this choke does on the line
The Siemens 4EU4551-0AM10-0A is a 3-phase output choke rated for 690 V with a continuous current of 1000 A at 50 Hz. It sits between the drive output and the motor cable, limiting the rate of voltage rise (dV/dt) and reducing reflected-wave peaks on long cable runs — a common failure driver on high-power VFD installations. Designed per EN 60289, it handles the switching frequencies typical of modern IGBT drives without saturating the core.
The 1000 A continuous rating at 50 Hz defines the thermal limit for motor-side current. At higher switching frequencies (common in modern drives), derate the choke per the manufacturer's curve — the 1000 A figure assumes a 50 Hz fundamental. IP00 means no ingress protection; the choke must live inside a clean, dry enclosure. The 0.01 mH inductance value is low — this choke is sized for high-current, low-impedance paths typical of large motors, not for filtering harmonics on the line side.
Mount the choke on a flat panel surface inside the drive cabinet. The flat-type terminals require busbar or compression lugs — no cage-clamp or screw terminals. Ensure adequate clearance around the IP00 body for natural convection cooling; forced airflow may be needed if ambient temperature inside the cabinet exceeds 40 °C (the rated operating ambient). The EN 60289 standard governs the choke's thermal and dielectric design, so the manufacturer's mounting and spacing recommendations in the datasheet are mandatory for compliance.
