More Information

Overview Manuals Drive Matching EMC Wiring Grounding Application
  • 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.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

  • 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
Description
Allen-Bradley 1336-RFB-30-A-4 is the equivalent catalogue notation for the officially documented 1336-RFB-30-A4 input RFI filter used with compatible 1336 adjustable-frequency AC drives.

The filter is installed between the incoming AC supply and the drive input terminals to reduce conducted radio-frequency emissions in the supply and ground wiring.

Confirm the official drive selection row, EMC enclosure requirement, panel-mounting arrangement, grounded supply type, cable shielding, and solid earth connection before installation.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
How does Allen-Bradley 1336-RFB-30-A-4 help with an EMC-related supply problem?
It reduces conducted RF emissions on the supply and ground path. It does not correct poor bonding, damaged shielding, or other sources of electrical noise.
Can Allen-Bradley 1336-RFB-30-A-4 be fitted to any 1336 drive in the panel?
No. Use the official model-to-drive selection table. Similar-looking 1336 drives can require a different filter and mounting arrangement.
Does Allen-Bradley 1336-RFB-30-A-4 replace a braking resistor or line reactor?
No. It is an EMC filter. It neither absorbs regenerative energy nor provides the impedance function of a line reactor.
Why does Allen-Bradley 1336-RFB-30-A-4 require a solid earth connection?
Filter operation can create earth-leakage current. Correct protective earthing supports personnel safety, equipment protection, and intended EMC performance.
Can Allen-Bradley 1336-RFB-30-A-4 be used on a grounded-delta supply?
No. The manufacturer specifically warns against using this RFI filter with a grounded-delta supply arrangement.
Why must motor and supply cables be shielded or armored with Allen-Bradley 1336-RFB-30-A-4?
Unshielded cable runs can radiate interference and undermine the filter’s benefit. Bond shields or armor at the documented points.
What installation arrangement matters most for Allen-Bradley 1336-RFB-30-A-4?
Mount the filter and drive as one assembly using the supplied hardware and the official Figure 2 layout; do not substitute an unverified panel arrangement.
