Siemens 6SL3203-0CD25-3AA0 Sinamics Line Reactor

Siemens 6SL3203-0CD25-3AA0 Sinamics Line Reactor is a 3‑phase, IP20‑rated inline impedance device designed to accompany the SINAMICS Power Module FSD 30 kW. It is rated for 480 V (3AC) input, 63 A, and supports 47–63 Hz operation, aligning with common industrial power systems. This line reactor provides input-side impedance to dampen voltage transients and reduce inrush currents, helping improve drive EMC performance and protect connected equipment. The unit is specified for PM FSD 30 kW power modules and offers a type rating based on the nominal base current (I_N), enabling selection based on the drive configuration. As part of Siemens’ SINAMICS line reactors, it is intended for indoor cabinet installation in industrial environments and complements SINAMICS PM configurations where reliable harmonic and surge suppression is required. Typical applications include speed control for motors on conveyors, mixers, and processing lines in 50/60 Hz facilities, where a compact, IP20 enclosure and 63 A rating provide compatible protection and performance for moderate-to-high-power drives.
