It smooths current harmonics and limits inrush, protecting both the drive's rectifier and the upstream distribution. Rated at 1120 A maximum and 1010 A continuous at 400/480 VAC, 50/60 Hz, it handles the full-load current of a large motor drive without saturating. This is a standard design point for drive input reactors; you coordinate it with the drive's DC-link inductance and any upstream transformer impedance. Thermal class H insulation, rated at 40 °C ambient. IP00 rating means open-frame — mount inside a rated enclosure.

Frequently asked questions
Will 4EU3651-7UC00-0A drop into a panel designed around a different line reactor?
The 0.35 m width, 0.321 m height, and 0.237 m depth define the footprint. The flat-type terminals require busbar or lug connections. Verify your panel's mounting hole pattern and clearance envelope against these dimensions — do not assume a drop-in fit without measuring.
