Siemens 6SE7027-2ES87-0FB1 Soft Starter Controller Module

Siemens 6SE7027-2ES87-0FB1 is an RI suppression filter designed for the SIMOVERT MASTERDRIVES vector-control drives, delivering EMI/RFI suppression on three‑phase power without altering the drive’s control signals. It accepts a 3‑phase input of 380–460 V and provides a 3‑phase connection in the 380–480 V range, with a current rating up to 80 A and compatibility with 50/60 Hz systems. As a MASTERDRIVES accessory described by Siemens as a noise-filter component (RFI/EFI/EMI) in the vector‑control family, it helps meet EMI performance requirements in industrial automation environments where clean power is crucial for reliable motor operation.
