The Siemens 4EU2732-0FV08-4BA0 is a 3-phase filter reactor rated at 25 kVAR reactive power at 690 V and 50 Hz, with a 14% p impedance. It's built to EN 61558, which covers the safety of power transformers, reactors, and similar equipment — so you know the insulation coordination and thermal limits are certified, not just guessed at. The 134 Hz resonant frequency tells you it's tuned to suppress the 5th harmonic (250 Hz) and its neighbors, which is the usual target for a six-pulse drive front end.
The 40 °C ambient rating (TA/ISOKL: 40 /H) means it's designed for continuous duty in a ventilated cabinet at that temperature — no derating needed up to 40 °C. Push past that and you'll need to drop the load or add airflow. The IP00 enclosure means it's an open-frame component: it goes inside a panel or cabinet, not out on the floor where dust or fingers can get to it. Terminals are flat-type, so you'll be landing ring or fork lugs, not bare wire under a screw.
The ripple voltage spec (110 /0 /6 /5) and the 14% p impedance are the numbers that matter for drive harmonics. A 14% p reactor is stiffer than the common 3% or 5% line reactors — it'll knock down more harmonic current, but it also drops more voltage across itself at full load. If you're swapping this into an existing drive cabinet, check that the DC bus still has headroom after the added impedance drop.
