The Siemens 4EU3652-2UA00-0AA0 is a 3-phase mains choke (Netzdrossel f. FU) designed for the input side of variable-frequency drives. It carries a maximum current of 630 A and a rated current of 567 A at 500 V AC, with an inductance of 0.029 mH and a relative inductive voltage drop of 2%. Thermal class H insulation (rated for 180 °C continuous) gives it headroom for sustained high-current operation in a drive cabinet.
Sizing and fit for a drive line
The 2 % voltage drop at rated current is the standard impedance for a line reactor sized to limit harmonic distortion and reduce peak currents into the drive's DC bus. At 567 A continuous, this choke is matched to a drive in the 315–400 kW range on a 400 V supply, or up to 500 kW on a 500 V supply — the operating voltage is rated at 500 V AC.
