The VW3SKLN125H270: The 125 A [In] rated current is the continuous RMS current the choke can carry without exceeding its thermal rise — sized for a drive input that draws up to that nominal current. The 0.27 mH inductance value determines the impedance at line frequency (50...60 Hz) and therefore the voltage drop and harmonic attenuation; at 50 Hz, the inductive reactance is about 0.085 Ω, producing roughly 10.6 V drop at 125 A (about 2.5 % of a 400 V line). The 87 W thermal losses mean that heat must be dissipated from the open frame (IP00) into the surrounding enclosure — the choke is not self-ventilated and relies on the panel's airflow. The IP00 rating means no protection against dust ingress or water — the choke must be mounted inside a clean, dry enclosure or cabinet. The 1.5 x nominal current overload capability for 60 seconds allows it to ride through short-duration drive inrush or motor acceleration without saturating the core.
