Product Description
The AD250 is a heavy-duty, dual-barrel aluminum mechanical terminal lug designed for high-capacity power distribution. Engineered to terminate two separate conductors into a single mounting point, this lug is a staple in industrial switchgear, motor control centers, and panelboards where high-density wiring and reliability are non-negotiable.
Manufactured from high-strength 6061-T6 aluminum alloy and finished with electro-tin plating, the AD250 provides maximum conductivity and superior resistance to oxidation. Its CU9AL (AL9CU) dual-rating ensures it is fully certified for use with both copper and aluminum conductors in demanding 600V to 35kV applications.

Key Features & Benefits
-
Space-Saving 2-Barrel Design: Consolidate two large 250 MCM feeders into a single mounting footprint, ideal for compact busbar and enclosure layouts.
-
Universal CU9AL Compatibility: Certified for both Copper (Cu) and Aluminum (Al) conductors, providing total field flexibility and preventing galvanic corrosion.
-
Superior Corrosion Resistance: The electro-tin plated finish provides a durable barrier against atmospheric oxidation, maintaining low contact resistance over the life of the connection.
-
Mechanical Efficiency: Features high-torque mechanical set screws that allow for secure termination using standard tools—no hydraulic crimping required.
-
Industrial Durability: Constructed from extruded aluminum for higher structural integrity than cast alternatives, ensuring the lug won't crack during high-torque installation.
