Air core chokes have a core of air or non-ferrous or non-conductive material. This makes them highly suitable for high frequencies and current limiting applications. Free of ferromagnetic materials, they avoid saturation, eddy current loss and hysteresis loss.

Air core chokes by MANGOLDT effectively limit switching peak inrush currents in reactive compensation and other capacitor based equipment. Optimally designed for the capacitor rated current, these chokes serve to dampen the incoming currents so as to safely protect the capacitors and their wiring.

MANGOLDT air core chokes serve as current limiting chokes mostly to limit short-circuit currents in downstream equipment. As a result, the switchgear, cables and other elements used can be designed for a much lower short-circuit power.
