Its job is to smooth the DC bus, limit current rise rates during commutation, and reduce harmonic distortion feeding back to the line. Rated for 230 V AC at 50 Hz, it carries a maximum continuous current of 36 A and a rated current of 32.4 A. The inductance is 0.00071 H, with a relative inductive voltage drop of 3.5% at rated conditions. The 36 A maximum rating sets the hard ceiling for the converter's input current; the 32.4 A rated value is the continuous duty point the choke is thermally designed for. Exceeding that continuously will push the iron-core and coil losses — 20 W and 13.6 W respectively — above the thermal class B insulation limit. IP00 means the choke has no enclosure — it's an open-frame component intended for mounting inside a cabinet where the panel provides the environmental seal. The screw-type terminals accept field wiring directly. Rated ambient temperature is 45 °C, which is typical for inside a closed electrical enclosure without active cooling. If your panel runs hotter, derate the continuous current accordingly per the thermal curve. ## Deployment context This choke mounts inside a control panel via its frame, not on a DIN rail. The 0.115 m depth, 0.097 m width, and 0.111 m height mean it occupies a footprint roughly 115 mm × 97 mm — plan for that volume plus clearance around the screw terminals for cable bending radius.","metaTitle":"Siemens 4EM5005-4CB00 Commutating Choke, 36A Max, 0.71mH","metaDescription":"Siemens 4EM5005-4CB00 commutating choke for converters. 1-phase, 230V AC, 36A max / 32.4A rated, 0.71mH, IP00, screw terminals.
