The Siemens SIDAC 4EU2752-0EK00-4BA0 is a 3-phase output reactor rated for 60 A continuous, 480 V AC, with a switching frequency of 8 kHz — built to sit between a variable-frequency drive and the motor to limit dv/dt and reduce reflected-wave stress on the winding insulation. It carries an inductance of 0.1 mH and a voltage drop (uk) of 19 %, sized for a 54 A line current at 40 °C ambient.
The 0.1 mH inductance and 19 % uk are tuned for drive-to-motor cable runs where the reflected-wave peak exceeds the motor's insulation tolerance — typical on long leads or with fast-switching IGBT drives. The 8 kHz switching-frequency rating matches the carrier frequency of most modern PWM drives; running a higher carrier would exceed the reactor's core design and saturate it. 60 A continuous at 40 °C ambient means this reactor handles a 30–45 kW motor at 400 V, depending on the drive's overload profile.
Thermal class and connection
Thermal class H (IEC 60085) means the winding insulation withstands a continuous hotspot temperature of 180 °C — a safety margin for drives running at full output current in warm cabinets. The flat-type terminals accept busbar or large cable lugs, not standard ring terminals; plan for a busbar interface on the panel layout. Total power loss splits between 54 W in the copper coil and 159 W in the iron core at rated load — that 213 W of heat must be ventilated out of the enclosure.
Compliance documentation
The reactor is built to EN 61558-2-20 and carries UL/CSA recognition — the evidence confirms UL/CSA-recognized status. No specific RoHS, REACH, or CE mark is stated on this listing, but the UL/CSA recognition implies the design meets North American safety standards for industrial control equipment.
