It is designed for use in power conversion systems — typically placed on the input side of a variable-frequency drive or a DC power supply to attenuate harmonics, limit inrush current, and provide some protection against line-side transients. Compliance with EN61558-2-20 covers safety requirements for chokes and reactors. The 0.5 mH inductance and 350 A continuous current rating define the choke's core sizing. At 350 A, this choke is sized for a drive or converter in the 160–200 kW range on a 400 V three-phase system (typical rule of thumb: 3% impedance at 50 Hz). The 0.5 mH value gives a specific impedance at line frequency — about 0.157 Ω at 50 Hz — which determines the voltage drop and harmonic filtering effectiveness. If your drive's input current exceeds 350 A, you need a larger choke; if it is significantly lower, the choke will still work but the percentage impedance (and thus voltage drop) will be higher than the design point. The IP00 rating means it must be mounted in a clean, dry, enclosed panel — no washdown, no outdoor exposure without a separate enclosure. Flat-type terminals are the connection method — expect busbar or large cable lugs, not spring-cage or screw-clamp. The choke has no mounting bracket dimensions listed. The EN61558-2-20 standard covers thermal class and insulation coordination — the choke is rated for a maximum ambient temperature of 40 °C.","metaTitle":"Siemens 4EU2552-5GA00-0AA0 3-Phase Choke, 0.5 mH, 350 A, IP0","metaDescription":"Siemens 4EU2552-5GA00-0AA0 3-phase line choke, 0.5 mH inductance, 350 A rated current, IP00 enclosure, flat-type terminals.
