Overview

The ABB ADR-ALCUL Type Anti-Rotational Single-Conductor Lug, SKU ADR21AR, is engineered for reliable electrical connections in industrial settings. This one-hole mount lug is designed to accommodate a conductor range from a minimum of 14 AWG up to a maximum of 2/0 Str. Its key feature is the anti-rotational design, which ensures a secure and stable connection, preventing conductor spin-out during installation and under vibration. The lug is constructed from tin-plated material, offering excellent conductivity and corrosion resistance, crucial for maintaining connection integrity over time. It features a standard 1/4 inch bolt hole for straightforward mounting to busbars, equipment, or other termination points. As a single-pole (1 pole) connector, it is ideal for terminating individual conductors in power distribution systems, motor controls, and other electrical assemblies where a single, robust connection is required. The ADR-ALCUL series from ABB Installation Products is recognized for its practical design and dependable performance in electrical infrastructure. This lug's specifications make it suitable for a variety of applications where secure, single-conductor termination is paramount. The tin plating provides a protective barrier against environmental factors, ensuring long-term electrical performance and reducing the need for frequent maintenance. Its robust construction and precise engineering contribute to the overall reliability of the electrical system it's integrated into. The 1/4 inch bolt hole size is a common standard, facilitating compatibility with a wide range of mounting hardware and busbar configurations. When specifying electrical components, the ADR-ALCUL lug offers a straightforward and effective solution for single-conductor terminations.
