It limits current rise and reduces harmonic distortion on the AC line side of a variable-speed drive or rectifier. Rated for 400 V AC at 50 Hz, it carries a maximum AC current of 24 A and a rated AC current of 21.6 A. The inductance is 2 mH, with a relative inductive voltage drop of 4% at rated conditions. This is the part that sits between the supply and the converter input — not a filter choke for the DC link. The 24 A AC maximum current and 21.6 A AC rated current define the continuous load capability. The 29.4 A DC rated value tells you the choke can handle a higher DC-side current — typical when the converter draws pulsed current. The 4% inductive voltage drop is the impedance at rated current; a higher drop means more smoothing but also more voltage loss. Thermal class B means the winding insulation withstands 130 °C hot-spot temperature. The total power loss sums to 53.5 W (19.8 W coil + 33.7 W iron core), which must be dissipated — IP00 means no enclosure, so mount it in a ventilated cabinet or panel with clearance for airflow. This choke is a panel-mount component — no DIN-rail clip, no enclosure. The screw-type terminals accept standard power wiring; expect to land line and load conductors directly. Dimensions are 0.129 m deep, 0.097 m wide, 0.111 m high. Plan for mounting feet or a bracket; the IP00 rating means it is not touch-safe, so locate it inside a locked cabinet or behind a panel door. The 40 °C ambient rating is the standard industrial derating baseline — above that, reduce current per the thermal curve.","metaTitle":"Siemens 4EM5100-2CB00 Commutating Choke, 24A AC, 2mH, 400V","metaDescription":"Siemens 4EM5100-2CB00 single-phase commutating choke for converters.
