Rated 500 V AC at 50 Hz with a continuous current of 13.5 A (max 15 A), it provides 4.2 mH inductance and a 4 % relative inductive voltage drop at rated conditions, which keeps the converter's commutation notches within acceptable limits. Connections are via screw-type or tab terminals, typical for power wiring up to the rated 13.5 A. The 13.5 A rated current (15 A maximum) sets the continuous load limit for a single-phase converter input. If your drive draws more than 13.5 A RMS, this choke saturates and loses inductance — so size it to the converter's line-side current, not the motor nameplate. Thermal class B insulation (130 °C rise) and a total power loss of 41.8 W (13.9 W coil + 27.9 W iron core) at 40 °C ambient mean the choke dissipates heat into the panel. Account for that in your enclosure's thermal budget — it's not a negligible load. If your converter requires a lower drop (e.g., for high-torque low-speed operation), this choke may not fit. No official successor or phase-out date is recorded. Footprint: 0.115 m depth × 0.097 m width × 0.111 m height. It's not DIN-rail mountable — expect to bolt it to a panel baseplate or mounting bracket. The screw/tab terminals accept ring or fork lugs; leave clearance for the tab connectors on the side.","metaTitle":"Siemens 4EM5008-0CK00 Commutating Choke, 13.5 A, 500 V, 4.2","metaDescription":"Siemens 4EM5008-0CK00 commutating choke for converters, 1-phase, 500 V AC, 13.5 A rated, 4.2 mH, IP00, screw/tab terminals.
