It's built for IP00 open-chassis mounting with flat-type terminals — a line reactor sized for a 36.8 A converter input, not a general-purpose filter. The VDE 0550 compliance tells you it's designed to the German standard for transformers and chokes, which is the spec sheet you want for a panel destined for CE-marked machinery. The 36.8 A continuous rating (I LN) is the thermal limit at 40 °C ambient — that's the number to match against your converter's input current, not the peak or inrush. The 0.76 mH inductance and 4% impedance (UK) define the voltage drop and harmonic attenuation; a 4% choke is a common value for reducing current distortion on a 6-pulse rectifier front end. Flat-type terminals accept busbar or cable lug connections, typical for higher-current power paths. ## Deployment Context This choke sits between the AC line and the converter's rectifier input — typically a DC drive or VFD. It's a single-phase device, so for a three-phase converter you'd need three units, one per phase. The 230 V rating matches a single-phase line supply or a phase-to-neutral tap on a 400 V three-phase system. Mount it close to the converter input; long cable runs between choke and drive defeat the harmonic filtering.","metaTitle":"4EM5007-5CB Commutating Choke, 230V 36.8A, Mature Lifecycle","metaDescription":"4EM5007-5CB commutating choke for converter, 1-phase, 230V, 36.8A, 0.76mH, IP00, flat terminals.
