The 36 A rated current (40 A max) sets the continuous thermal limit at 40 °C ambient. Push beyond that and the winding temperature rises above the Class B (130 °C) insulation limit per IEC 60085, shortening life. The 18 W coil loss plus 26 W iron core loss — 44 W total at rated load — must be dissipated in the enclosure; at IP00 (open-frame), forced airflow or at least 100 mm clearance to adjacent metal is the rule in a panel. The 0.7 mH inductance is sized for a 4 % voltage drop at rated current and 50 Hz — a common design target for commutating chokes in 6-pulse drives. That impedance limits the peak fault current during a shorted output device, but it also drops about 9 V at full load. Verify the converter's minimum DC-link voltage under load; a 230 V input with this choke still leaves roughly 221 V RMS before the rectifier, which is fine for most standard 230 V drives. ## Mounting and connection The 97 mm wide × 111 mm tall × 129 mm deep footprint is a standard open-frame choke — no DIN rail clip, no flange. It sits on a panel or sub-plate via its own mounting feet (not detailed in the spec, but typical for this Siemens series). Screw-type terminals accept the main circuit wiring; no auxiliary terminals for thermistor or fan control. IP00 means no housing, so it must live inside a clean, dry enclosure — not on the shop floor or in a washdown zone.","metaTitle":"Siemens 4EM5107-7CB00 Commutating Choke, 40A, 230V AC, 0.7mH","metaDescription":"Siemens 4EM5107-7CB00 commutating choke for converters. 1-phase, 230V AC, 36A rated (40A max), 0.7mH, IP00.
