Rated for 400 V AC at 50 Hz, it carries a continuous rated current of 45 A with a maximum of 50 A — meaning it can handle nominal motor-drive loads up to roughly 22 kW (assuming typical drive efficiency) and still absorb transient spikes without saturating. The 0.28 mH inductance and 2% relative inductive voltage drop are sized for standard 6-pulse rectifier front ends; the 2% drop keeps the DC bus voltage from sagging noticeably under load. Thermal class B (130 °C rise over 40 °C ambient) means the choke can run at full rated current in a 40 °C enclosure without exceeding the insulation temperature limit — no forced cooling required in most panel layouts. The total power loss of 62 W (50 W coil + 12 W iron core) is modest; plan for natural convection clearance around the unit. IP00 protection means the choke is open-frame — it relies on the panel enclosure for dust and touch protection. Screw-type terminals accept typical power cable sizes; no special lugs needed.","metaTitle":"Siemens 4EP3700-5DS00 Commutating Choke, 400V 45A 3-Phase, I","metaDescription":"Siemens 4EP3700-5DS00 commutating choke for converter duty, 400V AC, 45A rated, 50Hz, 3-phase, IP00, screw terminals.
