It's built to EN 61558-2-20, the safety standard for chokes and reactors, so it's certified for permanent installation between the mains supply and a variable-frequency drive or soft starter. Rated for a 525 V line voltage, 68 A continuous line current (I LN), and an inductance of 0.975 mH per phase. The ITHMAX rating of 75 A at 50 Hz tells you the thermal current capacity — this is the continuous RMS current the choke can handle at its fundamental frequency without exceeding its temperature rise. At 50 Hz it's 75 A; at 60 Hz the same thermal limit applies, so you get a bit more headroom on the inductive impedance. The IP00 enclosure means it's an open-frame component — no splash or dust protection. Terminals are screw/flat-type, so you'll need ring or fork lugs sized for the cable you're running. ## Sizing and deployment At 68 A line current, this choke pairs naturally with a drive rated around 37–45 kW at 400 V or 45–55 kW at 525 V — but always check the drive manufacturer's recommended line reactor sizing for your specific model. The 0.975 mH inductance per phase gives roughly 3–4% impedance at 50 Hz on a 400 V system, which is the sweet spot for harmonic mitigation on most PWM drives without dropping too much voltage across the reactor. The TA/ISOKL rating of 40 / H means maximum ambient temperature of 40 °C with natural convection cooling.","metaTitle":"Siemens 4EU3032-0CA00-0AA0 3-Phase Line Choke, 525V, 68A, 0.","metaDescription":"Siemens 4EU3032-0CA00-0AA0 3-phase line choke, rated 525V, 68A, 0.975mH, 75/50Hz.
