- Reduces conducted radio-frequency emissions in the incoming supply and ground wiring
- Officially selected for documented 380–480 V 1336 PLUS, PLUS II, FORCE, and IMPACT drive ranges
- Panel-mounts with the drive as one assembly using the supplied Figure 2 hardware
Allen-Bradley 1336-RFB-30-A-4 is the equivalent notation for the official 1336-RFB-30-A4 Input RFI Filter designed for compatible Bulletin 1336 adjustable-frequency AC drives.
It connects between the AC supply and drive input terminals to limit conducted radio-frequency emissions into supply and grounding conductors.
Before installation or replacement, verify the official drive-selection row, -AE enclosure or EMC-kit requirement, Figure 2 mounting, supply arrangement, shielding, and protective earth connection.
Availability, condition, price, and shipping time for 1336-RFB-30-A-4 are confirmed during quotation.

- Use the official A4 selection row for 1336S/F-BRF75–BRF200 drives
- Use the same selection row for 1336E-BRF75–BRF100 drives
- Confirm an -AE enclosure option or the documented 1336x-AEx EMC Enclosure Kit
- Connect incoming AC supply conductors to the filter before the drive input terminals
- Route incoming supply cabling in conduit or use shielding or armor with equivalent attenuation
- Bond cable shield or armor to the filter, drive, and motor case as documented
- Provide a solid protective-earth connection because the filter can generate ground-leakage current
- Use only a nominally balanced, grounded AC supply arrangement
- Do not use the filter with a grounded-delta supply
- EMC-focused 1336 PLUS and PLUS II drive installations within the official A4 selection range
- EMC-focused 1336 FORCE drive installations within the official A4 selection range
- EMC-focused 1336 IMPACT drive installations within the official A4 selection range
