Rated for 400 V AC at 50 Hz, it carries 25 A continuous AC (28 A max AC) and 34.3 A DC, with a peak current capability of 35 A. The 0.79 mH inductance and 4% relative inductive voltage drop define the filtering characteristic for the converter's commutation circuit. The 25 A AC rated current (I LN) is the continuous thermal rating at 40°C ambient — this is the number you size against the converter's line-side current, not the 35 A peak which is a surge capability. The 34.3 A DC rating tells you the choke can sit in the DC link at that current without saturating. Thermal class B (130°C) winding insulation means the choke can run hot in a sealed cabinet as long as ambient stays at or below 40°C; total losses are 62 W (53 W coil + 9 W iron core), so factor that into your enclosure ventilation. This is an IP00 open-frame choke — no enclosure, so it mounts inside a cabinet with clearance to live parts. The screw-type terminals accept standard lug connections for the main circuit. Dimensions are 0.178 m wide by 0.153 m tall by 0.105 m deep; plan for at least 50 mm clearance around the core for airflow and magnetic field coupling to adjacent steel panels.","metaTitle":"Siemens 4EP3701-6DS00 Commutating Choke, 3-Phase 400V 25A","metaDescription":"Siemens 4EP3701-6DS00 3-phase commutating choke for converters.
