Line Reactor for Variable-Frequency Drives
The Siemens 4EU3652-8UC00-1BA0 is a three-phase mains choke (Netzdrossel f. FU) for variable-frequency drive inputs. It carries a rated current of 720 A continuous and can handle peaks up to 800 A at 40 °C ambient, thermal class H. The 2 % relative inductive voltage drop at rated conditions suppresses harmonics and limits inrush without excessive voltage drop under load.
Mounting and Integration Constraints
IP00 — no enclosure, no drip shield. This choke lands inside a cabinet, not on the wall. Dimensions are 0.35 m wide × 0.321 m tall × 0.237 m deep; verify panel floor space and busbar clearance before the outage window closes. Main circuit connection uses flat-type terminals, so the mating busbar or cable lug needs to match that interface — no ring terminals or spring clamps here.
