It sits between a variable-frequency drive and the motor to smooth the PWM waveform, reduce voltage spikes, and limit capacitive charging currents in long cable runs — protecting both the drive output stage and the motor windings. Rated frequency is 8,000 Hz. The 49A maximum current rating sets the drive output size this reactor can handle — match it to a drive whose rated output current does not exceed 49A in continuous duty. The 0.5 mH inductance value determines the impedance at the switching frequency; higher inductance gives more attenuation but also more voltage drop and physical size. At 8 kHz, 0.5 mH provides meaningful dv/dt reduction without excessive core loss. Power loss is 205 W in the coil and 160 W in the iron core at rated operating point. IP00 enclosure requires mounting in a ventilated cabinet with ambient at or below 40°C. Thermal class H insulation (180°C hot-spot rating per IEC 60085) gives headroom above the 40°C ambient, so the reactor can handle overload conditions and higher switching harmonics without accelerated aging. The flat-type terminals (flat connector) for the main current circuit are designed for bus-bar or heavy-gauge cable lugs — not for standard ring terminals. Plan your panel wiring accordingly. ## Where you use it Installed between drive output and motor, typically inside the drive cabinet or a separate enclosure close to the drive. Dimensions are 0.3 m wide, 0.26 m tall, and 0.21 m deep — factor that into your cabinet layout, especially if you are retrofitting into an existing panel with tight clearances.","metaTitle":"Siemens SIDAC 4EU3052-0AL00-0AA0 Output Reactor, 49A, 8kHz","metaDescription":"Siemens SIDAC 4EU3052-0AL00-0AA0 output reactor, 3-phase AC, 49A max, 8kHz rated frequency, 0.5mH, IP00.
