It sits between the supply and the drive rectifier, smoothing current harmonics and limiting inrush peaks so the drive doesn't hammer the upstream transformer or trip nuisance breakers. Rated for 224 A maximum AC current and 202 A continuous operational current at 400/480 VAC, 50-60 Hz, this choke handles the full input of a 110–132 kW drive class (depending on line voltage and motor load profile). The 62 µH inductance (0.0629 mH) with a 2% relative inductive voltage drop means it provides moderate harmonic attenuation — enough to meet typical IEEE 519-2014 guidelines for a 6-pulse drive without over-sizing the reactor for the cable charging current. ## Thermal and mounting reality — IP00, Class H, 186 W to shed IP00 means no enclosure — this choke is an open-frame component intended for a ventilated cabinet. It sheds 186 W total loss (134 W copper + 52 W iron core) at rated load, so plan for forced air or natural convection with at least 100 mm clearance around the sides and top. The 0.225 m width and 0.176 m depth footprint fits a standard 600 mm deep panel, but the 0.21 m height needs vertical rail space. Class H insulation (180 °C) means the winding can survive sustained overloads that would cook a Class B or F choke — useful if the drive occasionally pulls above nameplate for short-duration loads like crusher start or conveyor breakaway. The 40 °C ambient rating is standard; above that, derate the current per IEC 60076-6. Termination is flat-type connectors (bus-bar style), not ring lugs or spring cages. The panel builder needs to plan for bolted copper bars or compression lugs sized for 224 A — no quick-connects here. ## Lifecycle and compliance — active, UL/CSA, EN 61558 It carries UL/CSA recognition per the description and is designed to EN 61558-2-20 (safety of transformers, reactors, and power supply units). That covers the insulation coordination and short-circuit withstand for industrial installations. RoHS and REACH compliance is standard for Siemens industrial components from this era.","metaTitle":"Siemens 4EU2552-8UA00-0AA0 Mains Choke, 224A, 62µH, 400/480V","metaDescription":"Siemens 4EU2552-8UA00-0AA0 mains choke for frequency converters. 3-phase, 224A max, 62µH, 400/480V, 50-60Hz.
