The Siemens 4EU3032-0MW08-1BA0 is a 3-phase filter reactor rated 70 kVAR at 690 V and 50 Hz, with a 7% p impedance. That 7% p figure is the per-unit impedance on the reactor's own base. The reactor is built to EN 61558-2-20, the standard for chokes and reactors, and carries an IP00 enclosure rating — meaning it is an open-frame component intended for installation inside a cabinet or panel, not for standalone outdoor or washdown duty. Terminals are flat-type, sized for lug or bus-bar connections typical of power-distribution assemblies. The resonant frequency is listed at 189 Hz. That places the series-resonant point well below the 5th harmonic (250 Hz at 50 Hz fundamental), so the reactor presents a high impedance to the dominant 5th and 7th harmonic currents — exactly where a line reactor does its work in a 6-pulse drive system.
At IP00 and with flat-type terminals, this reactor mounts inside a cabinet on a base plate or chassis — no DIN-rail clip, no enclosure of its own. The 70 kVAR rating at 690 V implies a full-load current around 59 A per phase (70,000 VAR / (690 V × √3)), so the flat terminals and bus-bar connections are appropriate for that current class. Plan for adequate ventilation: a reactor of this kVAR class dissipates several hundred watts as heat, and the IP00 open-frame design relies on cabinet airflow, not a fan on the reactor itself. The 7% p impedance means the voltage drop at rated current is about 7% of 690 V, or roughly 48 V line-to-line. That drop must be accounted for in the drive DC-bus voltage calculation — the rectifier sees about 652 V AC instead of 690 V, which lowers the theoretical DC bus from ~975 V to ~922 V. For a 690 V drive that needs full output voltage, verify the drive's DC-bus margin or consider a lower-impedance reactor.
