Siemens 6SE6400-4BC12-5CA0 Siemens
Overview
Product Overview The Siemens 6SE6400-4BC12-5CA0 is an external braking resistor for use with SINAMICS V20 AC drives (frame size FSC). It dissipates regenerative energy from the motor's DC link to enable controlled braking. It is compatible with 200-240 V single-phase converters, delivering continuous braking support in drive systems. Commonly applied in machine tool, conveyor, packaging, and basic drive installations where deceleration performance is required.
