Line reactor for SINAMICS G120C frame size FSB

Line reactors smooth the current drawn by the converter and thus reduce harmonic components in the line current. Through the reduction of the current harmonics, the thermal load on the power components in the rectifier and in the DC link capacitors is reduced as well as the harmonic effects on the supply. The use of a line reactor increases the service life of the converter.

If the ratio of the rated converter power to the line supply short-circuit power is less than 1 %, then it is recommended to use a line reactor to reduce the current peaks.

A DC link reactor is integrated in the SINAMICS G120C compact converter frame sizes FSD to FSF and therefore no line reactor is required.
