Siemens 6SE7031-8ES87-0FA1 Masterdrives Suppression Filter

Siemens 6SE7031-8ES87-0FA1 SIMOVERT MASTERDRIVES Suppression Filter is a radio interference suppression filter (A1) intended for SIMOVERT MASTERDRIVES Vector Control and Motion Control systems. It accepts three-phase power in the 380–460 V range at 50/60 Hz and is rated for up to 190 A, providing EMI attenuation to protect downstream equipment and help meet EMC requirements in demanding industrial environments. This Masterdrives suppression filter is designed for use with SIMOVERT MASTERDRIVES VC/MC configurations, helping reduce conducted and radiated interference in automated manufacturing, machine tools, and other motion‑control applications that rely on precise motor control. As a legacy Siemens component, the 6SE7031-8ES87-0FA1 is no longer produced by the manufacturer and is commonly found through distributors or refurbishers for existing installations.
