The Siemens 4EU3622-5CA00-0AA0 is a commutating choke for converter applications, designed for 3-phase AC systems. It carries a rated voltage of 500V and a maximum AC current of 450A at 50Hz, with an inductance of 62µH. The IP00 rating means it's an open-frame component intended for installation inside a panel or enclosure — not for washdown or outdoor duty. Thermal class H insulation (rated for 180°C continuous) gives it headroom in high-ambient converter cabinets where standard class B or F chokes would derate.
What the ratings mean for fit
The 450A AC maximum current (at 50Hz) sets the thermal limit for continuous operation in a converter line. The 405A AC operational current is the figure to size against your drive's continuous output — if your converter draws 400A RMS at full load, this choke sits right at the working point with margin. The 563A peak current rating covers short-duration transients during commutation, which is the actual stress event a commutating choke sees. The 4% relative inductive voltage drop at rated current tells you how much voltage the choke consumes at full load — 20V out of 500V — which your drive's DC-link design needs to account for.
Integration notes
Physical footprint: 0.35m wide × 0.321m tall × 0.227m deep. The main circuit connects via flat-type terminals — expect bus-bar or heavy cable lugs, not screw-clamp blocks. IP00 means no built-in touch protection; mount it inside a locked cabinet with proper clearance to grounded metalwork. The 293W coil loss plus 171W iron-core loss means about 464W total heat to vent at full load — factor that into your cabinet cooling calculation, especially if the converter and other heat sources share the same enclosure.
