Flat-type terminals suit busbar or large-cable connections typical of high-current drive inputs. The 400 A AC maximum current and 360 A rated operational current tell you this choke is sized for a drive drawing up to that continuous current. The 2% voltage drop is typical for a line reactor that limits harmonic distortion and reduces inrush — it smooths the current waveform seen by the drive's DC bus. The 45 µH inductance is relatively low, which means the choke offers moderate impedance at line frequency; its main job is to blunt high-frequency switching noise from the drive reflecting back onto the supply. The 179 W coil power loss plus 58 W iron core loss total about 237 W of heat to dissipate inside the panel — factor that into your enclosure cooling. Thermal class H means the winding insulation can handle 180 °C hot-spot temperature, giving headroom for overloads or high ambient conditions up to 40 °C. At 0.27 m wide, 0.248 m high, and 0.208 m deep, this choke occupies a substantial footprint — it is not a DIN-rail component. It is designed for bolt-down mounting inside a cabinet, with flat-type terminals for the main current connections. The IP00 rating means no ingress protection; the choke must be housed in a panel with at least IP2X or better to prevent accidental contact. Given the 237 W total heat dissipation, ensure adequate ventilation or forced-air cooling in the enclosure.","metaTitle":"Siemens 4EU2752-4UA00-1BA0 Mains Choke, 400 A, 500 V, 45 µH","metaDescription":"Siemens 4EU2752-4UA00-1BA0 mains choke for frequency converters. 3-phase, 400 A AC max, 500 V, 45 µH, IP00.
