The inductance is 1.1 mH, and the relative inductive voltage drop is 4% at the rated operating point. The thermal class is B (130 °C rise) per IEC 60085, with a rated ambient temperature of 40 °C. Total power loss splits between the coil (52 W) and the iron core (10 W), which should be factored into the cabinet thermal budget. ## Sizing and Application Context Mount this choke in the AC line between the supply and the converter's rectifier input. The 4% voltage drop at rated current is the design target for limiting harmonic distortion and reducing di/dt stress on the converter's input diodes. For a 400 V three-phase system, the 22.5 A rating typically matches a converter driving a motor load in the 11–15 kW range, depending on the drive's input current profile. The physical footprint is 0.178 m wide × 0.153 m high × 0.105 m deep. Panel layout must allow clearance around the IP00 core and terminals for airflow and tool access to the screw connections. At DC rated value, the choke handles 30.6 A — this is the current it can sustain if the converter operates in a regenerative or DC-link configuration, though the primary rating is the AC line current.","metaTitle":"Siemens 4EP3701-0DS00 Commutating Choke, 22.5A, 3-Phase, 400","metaDescription":"Siemens 4EP3701-0DS00 commutating choke for converters. 22.5A rated, 25A max, 3-phase, 400V AC, 50Hz.
