It is a 3-phase, 400 V AC rated component with a maximum continuous current of 22.4 A and a rated current of 20.16 A at 50 Hz. The 1.2 mH inductance (1.24 mH per the description) with a 4% relative inductive voltage drop at rated current means this choke provides meaningful impedance to smooth the DC link and protect the converter's input rectifier from current spikes. The 49 W coil loss plus 12 W iron core loss (61 W total) must be considered in the enclosure thermal budget — at IP00, this unit is intended for mounting inside a ventilated cabinet, not in a washdown or dust-tight environment. Screw-type terminals are used for the main circuit. The IP00 rating requires installation inside an enclosure. Width is 0.178 m, height is 0.153 m, and depth is 0.105 m. ## DC Rating Note The DC rated value is 27.4 A. The primary operating voltage is 400 V AC.","metaTitle":"Siemens 4EP3700-8DS00 Commutating Choke, 22.4 A, 400 V AC","metaDescription":"Siemens 4EP3700-8DS00 commutating choke for converter duty. 3-phase, 400 V AC, 22.4 A max, 1.2 mH.
