ADR11

Overview

The Blackburn ADR11 is a dual-rated mechanical lug designed for aluminum and stranded copper conductors ranging from 14 to 1/0 AWG. It features a single-conductor, one-hole mount configuration with a 1/4-inch stud interface. The connector utilizes tin-plated surfaces to ensure low contact resistance and includes an extra aluminum lug for enhanced performance. Installation requires no special tools, relying on slotted screw-on lugs that accommodate conductors up through 2/0 stranded wire.

Feature Summary

• Dual-rated construction supporting both aluminum and stranded copper conductors
• Tool-free installation process utilizing slotted screw-on lugs
• Tin-plated finish engineered for low electrical contact resistance

Applications

• Connecting aluminum or copper conductors in electrical distribution systems
• Mounting equipment requiring a single-hole terminal interface
• Industrial automation power connections

Procurement Notes

Verify the specific conductor material compatibility (aluminum vs. copper) and gauge range against project specifications. Confirm the mounting hole diameter matches the required 1/4-inch stud size. Ensure the application environment aligns with the tin-plated finish limitations. Cross-reference the part number with official manufacturer catalogs to confirm current availability and technical revisions before finalizing procurement orders.

Selection Notes

Select this component when a dual-rated mechanical connection is required for conductors between 14 and 1/0 AWG. It is suitable for applications where tool-free installation is preferred over compression methods. Ensure the mounting configuration supports a single-hole setup. Verify that the 1/4-inch stud dimension fits the target equipment interface. Consider the tin-plated finish for corrosion resistance in standard indoor environments.

Part Context

This component belongs to the Blackburn ADR Series, a line of mechanical connectors distributed under the Thomas & Betts brand by ABB. The series provides solutions for overhead distribution and grounding needs. The ADR11 specifically addresses single-conductor mounting requirements within the broader portfolio of dual-rated aluminum and copper connectors.

Replacement Considerations

Public confirmed substitute part numbers include ADR11-21 for two-conductor applications. Verify dimensional compatibility and stud size equivalence before substitution. Ensure the replacement maintains the same dual-rated conductor support capabilities.
