It limits current rise and harmonics on the input side of a variable-frequency drive or DC drive, protecting the converter's rectifier and smoothing the DC link. Rated for 400V AC at 50Hz, it handles a continuous AC current of 18A (20A max) and a DC rated current of 24.5A, with an inductance of 2.4 mH and a relative inductive voltage drop of 4% at rated conditions. The 4EM5005-7CB00 is rated for 400V AC, 50Hz — standard European mains for a single-phase converter input. The 18A continuous AC rating (20A max) tells you the maximum RMS current the choke can pass without saturating or overheating; size it for the converter's input current, not the motor's full-load amps. The DC rating of 24.5A covers the DC-link side if you're using it post-rectifier. The 2.4 mH inductance and 4% voltage drop are the key numbers for harmonic mitigation — this choke provides moderate impedance, enough for most small to mid-size drives in a typical industrial panel. Thermal class B (130°C rise) means the winding insulation handles standard industrial ambient temperatures up to 40°C without derating. The total power loss is about 37.7W (18W coil + 19.7W iron core) — that's heat that stays in the panel, so factor it into your enclosure cooling calculation. This is an open-frame choke with IP00 protection — no enclosure, no drip shield. Dimensions are 0.115m deep, 0.097m wide, 0.111m high — a compact footprint that fits most standard panel layouts. Connections are screw-type or tab terminals for the main circuit, which is straightforward for panel wiring.","metaTitle":"Siemens 4EM5005-7CB00 Commutating Choke, 400V 20A 2.4mH","metaDescription":"Siemens 4EM5005-7CB00 commutating choke for converter, 1-phase, 400V AC, 20A max, 2.4mH, IP00, thermal class B.
