Allen-Bradley 22-RF021-BS Line Filter Assembly

Allen-Bradley 22-RF021-BS Line Filter Assembly is an EMC line filter kit designed for PowerFlex 4 drives. It provides EMI/RFI suppression on 3‑phase 200–240 VAC systems up to 21 A and features a short cable length to simplify wiring in compact control panels. Classified as a PowerFlex 4 Class Line Filter, it is intended to accompany PowerFlex 4 drives to help meet EMC requirements by filtering conducted emissions from the drive to the motor. Typical industrial applications include conveyors, pumps, fans, and other automation equipment where PowerFlex 4 drives are used and space is at a premium; the 22-RF021-BS offers reliable filtering for 200–240 VAC, 3‑phase operation in a 21 A circuit. This part number is part of Allen-Bradley’s EMC filter lineup for PowerFlex drives, delivering a compact, factory-supported solution for EMI control in panel installations.
