The 1.1 mH inductance and 6.1 % impedance (per the description) smooth the motor cable voltage reflections that cause insulation stress on long cable runs — a common issue with PWM drives. The IP00 protection class means it's an open-frame component intended for enclosure mounting, not standalone outdoor use. Thermal class H (180 °C insulation system per IEC 60085) gives it headroom for high-ambient or overload conditions up to 40 °C ambient.
This reactor installs between the VFD output and the motor. It's sized for a 3-phase AC motor load on a 400 V line (per the description). The flat-type terminals accept busbar or lug connections — plan for a panel layout that accommodates the 0.22 m width, 0.21 m height, and 0.16 m depth. The open IP00 frame needs to be inside a cabinet with at least IP54 to keep dust and moisture off the windings.
