Siemens 6SL3203-0CD21-4AA0 is a line reactor (AC commutation choke) for SINAMICS drives with base mounting. It is configured for 3-phase 200-480V AC service and has a 14A nominal current rating, intended for use with the SINAMICS Power Module FSB on 4.0 kW systems. The reactor smooths the incoming current and helps limit inrush, contributing to improved input power quality and EMI performance for the drive assembly. This is an official Siemens component designed to be installed between the mains and the drive input to enhance reliability in demanding industrial applications.
