Siemens 6SE7021-5FS87-1FE0 is a three-phase output reactor (filter) for SIMOVERT Masterdrives, designed for 500–575 V AC systems and rated at 17.5 A. The unit is specified with an output performance of FMAX = 300 Hz and FP = 3 kHz. The 5FS87 suffix indicates the 500–575 V version, distinguishing it from the 0ES87 variant used with 380–460 V systems. This Siemens component is intended for integration with SIMOVERT Masterdrives installations where a dedicated output reactor is required on the drive output.
