D3N - Three-phase line chokes
D3N line chokes are designed to work in three-phase, converting power supply circuits in numerous industrial applications. Often used for reducing the value of short-circuit or inrush current. They also operate as smoothing and filtering harmonics distortions chokes. D3N inductors consist of 3UI iron cores with air gap, a copper winding on a uniform bobbin, metal footing and electric terminals. Double vacuum impregnation provides high mechanical resistance and anti pollution barrier.
